The Fitbit Sense included, as part of it’s operation, the Google Assistant app, this Fitbit was more expensive but did not! Why?

After my Fitbit Versa 2 stopped working, I decided it was time to buy a nicer Fitbit. I had been eying the Sense 2 for quite sometime. The battery lasts for a week to a week and a half. It also seems to be a lot more accurate than the Versa 2. It also does not have any issues with Bluetooth pairing with my phone like the Fitbit versa 2 did. I snagged the Sense 2 when it was $70 off! I am overall pleased with my purchase. This is my third Fitbit, my others lasted 2-3 years. I’m hoping this one lasts just as long if not longer! If you are stuck between deciding on the Versa 4 or Sense 2, I would recommend getting the Sense 2 as it is more accurate and has more features!

La batería se acaba en al menos dos horas o dos horas y media.
Además la interfase es muy y lenta muy ineficiente. Significativamente representa un retroceso en el producto.
No lo recomiendo en lo absoluto.
Lo regresé.

Accurate time. Easy to setup, use, and charge. Synchronize to app on phone. May functions. Best of all it is water resistant to 10 meters.

Fitbit charges quickly, user friendly, looks great, has many tracking functions and by far the best. Fitbit user over a decade and received an Apple Watch as a birthday gift, but had to go back to my Fitbit. It’s not about the name, but getting the best quality for your bucks! It performs better for me than the Apple Watch.
Emily –
Ive had this watch for a week and the pros are so much more than the cons.
Battery life is amazing, lasted me 3 full days on one charge.
Love the customization of the watch faces.
The device is fast and all monitors work seemlessly EXCEPT the heart rate monitor. The heartrate monitor (depending on how saturated your tattoo ink is in the area) does not work through tattoo ink. You can see in my photos on my non dominant arm with tattoos it does not get a reading but on my dominant arm without tattoos it gets a reading.
If you have tattoos and plan on getting a smart watch this is not the one for you.

i was a diehard fitbit customer since 2016. over the past several years the quality has steadily degraded since google purchased fitbit and overhauled all the software that actually worked with the product. i would have recommended fitbit for years but now i would warn people against it.
Major cons: life/durability, connectivity and functionality
Durability: i bought my first fitbit sense in December 22 and it died by December 23. I bought this fitbit sense 2 in January 2024 and now it is experiencing the same charging issue. the charging prong connections get clogged over time due to sweat or dirt, but i cleaned this one more regularly than the previous one and it stopped charging much earlier. I can still kind of get the new one to work if I stand and hold the charger there and wiggle it around till it connects, then gently place it and make sure it doesn’t disconnect, but it is definitely on it’s way out. It used to stay charged for 5 days on one charge if I didn’t use GPS, now it is 2-3 days and I have to be super careful about not letting it get to zero because it is impossible to tell if it is connected once it dies fully. EDIT: I wrote this review July 20, 2024; as of August 20, 2024 the Fitbit sense 2 will not charge no matter what I do so I cannot even reset it or update it because it won’t turn on. Don’t waste your money (I also have 4 sense chargers & none work – it is definitely the watch)
Connectivity: every single time I open the fitbit app it is a fight to sync the device and takes probably about 15-30 mins on average to get to work. it is infuriating, and when it does finally sync, half the information doesn’t show up correctly so you have to try to run it again or wait another 15-30 minutes for that to show up. Two nights ago I was trying to sync for over 2 hours. This is really frustrating while I’m in the middle of a workout, especially a run where I don’t want to stop and fiddle with my watch/phone, or when I’m trying to quickly check my stats on the go
Functionality: This isn’t the WORST thing about it – it does its job for tracking for the most part. I have lost a lot of sleep data due to the connectivity and app issues though which was a big factor I purchased the sense rather than the apple watch initially so I’m annoyed about that. They also got rid of all the social features in the app in January. I also learned recently you don’t have to pay a premium subscription for a lot of the analytics (sleep, cardio health, etc) you do on Fitbit if you get a garmin or apple watch. Sometimes I feel like the tracking is lagging compared to its competitors, it feels like google is just stagnating Fitbit using its established consumer base until they can get more marketshare with the pixel watch.
Pros: appearance, comfort, technically does what it says, just not very well
All that being said, if it wouldn’t keep dying within a year of purchase and it would actually connect to my phone/the app actually worked I would probably buy another sense next just because I am familiar with it, it does the trick, and it has all my past data. However it doesn’t seem like that will be improving so I will have to switch on my next fitness tracker I have to buy, which will probably be quite soon unfortunately. EDIT: i will not ever buy a sense again actually, see previous edit

I have decided I need to be healthier. So this Fitbit helps me move and keeps me honest. I love the functionality of it. The small band is perfect for my small wrist. It’s easy to use and very accurate with all the stats.
Linley Maddick –
The media could not be loaded.
Para mi ha sido muy eficiente, no he tenido problemas para usarlo y no se ha trabado, lo que si es que incluye algunas funciones premium solo por un tiempo de prueba, y es algo que no te dicen antes de comprarlo. Recomiendo que compren una funda o protector de pantalla de esos como de goma dura porque si se raya si no tienes cuidado, pero en si cumple su función y además es fácil de usar
Sally –
The entire point I get these trackers is to help monitor my sleep and a couple months back this function just quit working.
Charges fast. Long batter life. Not too heavy. Connects just fine. Looks good depending on your watchband. There are good looking stainless steel bands that make you feel like you’re wearing a real watch with some substance.

This Fitbit smartwatch is a great deal for how much it offers. Our purpose for purchasing these are to keep track of our Heart Health…a great plus is that we are able to share records with our doctor.
The size is great, I am able to keep track of time without needing glasses.
We love that we are able to keep track of our sleep patterns, do an ECG and so much more …it focuses on how each individual body functions (great thing about smart watches) rather then using general information.
The one downside about this….it requires a subscription. Now it comes with a free 6month premium subscription…. it’s loaded with helpful action suggestions to keep your mind body and spirit strong. I believe the cost after the 6 month free trial is $79 a year …but well worth it for all the potential health benefits.
We like things simple …and even though it we are still figuring things out …this smartwatch is pretty simple to maneuver through.

I gave this watch a 5 star review because I do love my fit bit. I tried an Apple Watch, and actually wore both for a few days to check the accuracy and Fitbit was far better. The battery lasts days, where the Apple Watch needed daily charging. We did a step check too. Watching (from the app) each step and counts – comparing it to the watch Fitbit was spot on, apple was not. I would definitely recommend.

Good product . Switched from Apple Watch 8 ( which crashed after 2 yrs of use) and find this so superior in terms of battery life. Features are almost same but this is a improved version for a better price

I have worn my Sense 2 for a week now. Just absolutely love it. I do wish I had dug a bit deeper to find out that Apple does not sync for text messaging (apparently only Android does) but you do get call alerts. I’m a nerd when it comes to my own bodies statistics so getting to learn about my sleep, my skin temp, and track my walking and workouts has been so much fun.

This thing has changed my life for the better. I used to worry about my heart rate too much after I had heart surgery to fix AFIB, with this thing I can track it IN REAL TIME, ALL THE TIME, unlike the Apple Watch. The app is fantastic, so much data to mull over and improve on every single day. I never thought I’d get into cardio, but now I jog everyday to see how much further I can advance in heart rate, steps, miles, time, etc. It’s a wonderful product! However, there are a few quality control issues. The auto dim/screen brightness setting does not work after 3 days of ownership. Baffling. Sometimes the timer stops refreshing, making it appear the watch software has frozen, but it comes back to life after pressing the button. The UI could be smoother. 5 stars for the fitness tracking abilities, 3-4 stars for quality control issues.

Update to my previous review: Leaving at 5 stars for quality, durability, and features. Battery life seems to be about the same as my old Fitbit HR. Initially, I got about 5 days out of the first couple of charges. Now I’m getting about 3-4. I have no problem with that. I charge my phone more often so I don’t know why I would expect more from my fitness device. How quickly the battery drains seems to be dependent on my level of activity. I just check every day to see how much it’s drained so I don’t get caught out with a dead battery. Haven’t allowed it to go less than 20%.
It does not track steps accurately when I do pool exercises. I manually calculated about 2400 steps during my pool therapy and the tracker only counted a bit over 1900, including steps walking to and from the pool and so forth. All total, there should have been closer to 3000 steps so that’s a pretty big disparity. Frankly, I have not found any fitness tracker to be very accurate with step count during exercise as it depends on how much arm swing is involved.
Previous Review: Received my Fitbit Sense 2 (Mist blue and light gold) a few days ago and I love almost everything about this fitness tracker. The mist blue color is a pale blue-grey. The watch casing is a soft gold color like you might see on a car. It matches the seller’s photo perfectly (on my PC monitor anyway.) I think it’s very pretty, albeit larger than I like in a watch. I have tiny wrists and large watch bands/faces are awkward on me. But, to get the features I wanted, it’s worth getting used to. I don’t care for silicone bands as they don’t breathe but I suppose for a sport watch, it might be the best option. The buckling system was concerning for me because you have to pop the band hole over a pin, then tuck it under on the other side against your wrist. It looked like it would be uncomfortable to clasp it and wear, but I’m happy to say it’s not. Just feels a bit weird to me because it’s bulky for my wrist size.
It was relatively easy to set up. The only difficulty I had was when I logged into my Fitbit app previously associated with my Fitbit Charge HR, it kept asking me to log into my account, but I was already logged in. When I entered my password, it said it was incorrect but it wasn’t. I finally tried using my email PW and got into my account. What was confusing was, the Fitbit logo was at the top next to, “log into your account.” So, buyer be aware, if you have to log into an existing Fitbit account, they want your email address/PW, not Fitbit PW.
The biggest reason I chose this model was for water use. I have to do pool therapy and wanted all my steps and activities to be logged in real-time. I wore it in the pool, hot tub, and shower today and there were no problems with it at all. Just be sure to read all the instructions carefully. You can get more info on the Fitbit website for details on setup, use, and care. The device only came with quick setup instructions in the box.
I haven’t really paid much attention to the sleep tracking as I have a sleep number bed that tracks that. And I haven’t compared it against another heart rate monitor. However, based on the level of activity and how I felt during pool walking and exercises, it seemed like the numbers were relatively accurate.
My favorite feature is the hourly buzz to get moving. It not only buzzes on my wrist to alert me it’s time to move, but after I get up and walk around, it buzzes again to let me know I’ve completed 250 steps (based on my current setup.) This feature is priceless as I sit at a PC all day and forget to move.
Overall, 3 days in, I’m very happy with this purchase and feel that the price was fair compared to similar devices with the same features. It also came with 6 months of free premium app services which I appreciate because it gives me a good amount of time to decide if I want to continue with the premium for a monthly fee. I do not find that app either intuitive or user-friendly and it will take some time for me to get the hang of using it.
Should I run into any problems with my Sense 2 in the future I’ll update this review.

Overall it seems to be a great watch. I specifically bought this for my mother because she had a stroke and I wanted her to be able to check for a-fib. I also wanted her to be able to monitor her heart rate and oxygen levels.
Ecg- its finicky, you have to really play with the placement of your fingers in order to get it to start reading, then most of the time the results are inconclusive. This part of the watch is supposedly designed by cardiologists and approved for 98.8% accuracy. The process to actually see the ecg graph is unnecessarily difficult. Samsung does a much better job in this category.
The setup is easy, and straightforward. The app is also pretty straightforward and easy to use.
Overall its a pretty standard smartwatch, with a few extra health monitoring related features. If you’re looking for a watch to track a-fib, id probably steer away from this one. Otherwise it seems great.

This is my fifth Fitbit watch and by far the best. It’s slim and light weight and I hardly notice I’m wearing it. The display is easy to read and there’s a large assortment of watch faces available. I especially like the two-hour heart display instead of just the heart rate, and it’s convenient to have the weather on my wrist.
I only gave it 4 stars because of the band, which absolutely sucks. Where it tucks back in, it pinches my skin. I purchased a replacement band, the typical clasp type and it’s much, much better. Also, the battery lasts 3-4 days before it needs to be recharged, but it recharges quickly.
All-in-all, this is a great product, well worth its price.

I purchased this watch primarily for its continuous heart monitoring, ECG app, sleep monitoring, plus some basic fitness like steps and stairs.
It was easy to install. I was pleased to be able to turn off the GPS and Alexa which may have been good for an extra day of battery life. I was able to turn off the fitness nags. I’ve been running and working out over 40 years and don’t need nags. I was also able to skip the Premium service since I don’t want a monthly bill and don’t want other nagging.
There are a huge number of watch faces available. I focused only on free watch faces. One thing that wasn’t clear is that apparently you can only install 6 faces on the watch. When I found a better choice, it wouldn’t install and had no useful explanation of why not. I ended up looking specifically for watch faces that included a battery indicator (surprisingly not universal!) and basic fitness figures. The hard part was finding watch faces that increased the font size of the battery % and fitness figures so they were more easily legible to older eyes.
The biggest problem is with the watch band. I have a narrow wrist and bands with holes like the OEM band are never spaced in a way that fits well. So I ordered a new band that is metal mesh and uses a clamp to fix the length. That works to get a comfortable fit, but is a pain to put on. Good thing I only take the watch off once a day! So I tried another watch band that had a folding clasp, like my old watch band, and is adjusted in length by removing links. The whole process of removing links was a serious pain, requiring a magnifying ring light and great patience. And the link removal did not yield a snug and comfortable fit, just as with the OEM watch band. Back to the band that works, for now.
Update. I just discovered it is possible, apparently, to get an adapter from my old watch band that attaches to the watch with pins to the FitBit clamp system. I’m hoping that will allow me to use my old watch band which was excellent.
Further update:
https://www.amazon.com/dp/B0BN1RVM5W?psc=1&ref=ppx_yo2ov_dt_b_product_details
This adapter took a long time to arrive all the way from China, but it worked perfectly. My old watch band was a 20mm band with adjustable sizing clamp and a folding clasp to take it on and off:
https://www.amazon.com/gp/product/B08CY5D2LB/ref=pe_2313400_740551120_em_1p_0_lm?th=1
Now I have the best of all worlds. A good watch and it is easy to put on and take off with a snug fit. I wonder why no one seems to make this style of watch band specifically to fit the FitBit?

So far, this seens to be an incredible watch! Does everything I wanted it to do and the battery lasts quite a while! I wore it side by side with my Garmin Instinct, and they were pretty close in everything they measured like steps, sleep quality, stress, and heart rate. I bought the Fitbit because I wanted to have the ECG function, which the Garmin Instinct does not have. Overall, the Fitbit more than meets my expectations and works well, including accuracy! It’s also about half the price of the Garmin’s that do have ECG!

After trying out Garmin, Oura, and Apple Watch and returning to Fitbit (previously had the Charge version), I have to honestly admit that Fitbit is the best smartwatch. Starting from battery life, tracking steps and most importantly sleep. There are no hidden charges unlike the competitors. Highly recommend it, btw it also looks great.

After 5 years of good service my old Versa was struggling to keep a charge for 24 hours so I decided to replace it with a Sense 2. Huge mistake!
This device drops to 20% charge in about 12 hours and then requires charging for about 2 hours. You can wear it during the day or at night, but you really can’t do both unless you set aside a couple of hours for charging.
The watch has all sorts of sensors, but they all need to be turned off if you want 12 hours of life. Searching the message boards this seems common. I will play with the recommendations Insee there for a couple more days before returning it, but I’m not hopefull.
It is inexcusible for a company to try to market a product that falls so short of their written claims! Avoid Fitbit if you are looking for a smart watch!
Update: Turning off things like stress management and a restart apear to have imroved the battery life. Yesterday it dropped to about 60% including a 40minute walk with the GPS on. Unfortunately, it won’t charge back to 100% in the time it takes me to shower and dress like my old Versa. So it is probably a charge twise a day affair rather than the advertized once every 6 days. As others have remarked, the HR monitor seems to be incredibly inaccurate. It takes quite a while to react when starting a vigourous exercise and the HR laghs the obvioud signs like heavy breathing by several minutes. It barely registers exercises like the rowing machine in spite of the evident level of exertion. On a very steep hill that left me huffing and puffing it barely cracked into the fat burn zone. For some reason, the weather app has decided to stop working, too. The Google Maps shows turns that have nothing to do with the route being shown on the phone. This came and went, but I certainly wouldn’t trust it if I needed to get somewhere. I’m still quite dissatisfied. More later…
Well, I did get the weather app to work by turning location services to “always”. On days I don’t use GPS I can actually charge it during my morning shower and get close to 100%.
The heart beat monitor continues to be awful. My old Versa was often slow to recognize exercise, but the Sense 2 can take 10 minutes to even notice increased heart rate.
I started the trial offer on Premium but don’t see anything there that would persuade me to pay for it once the trial period ends.
Further update – for some reason, the Sense 2 has begun to mistake driving for bicycling. Based on it’s claims, I should easily win the tour de france. Pretty good for an old fat guy😃
Update after another month. The charging seems to have sorted itself out enough that I only need to charge once per day. The GPS IS some sort of random number generator, with the distance for the same exact walk varying by around 30% from day to day. Very brisk walks often show a slower pace than casual strolls.
The Sense has begun to begrudgingly acknowledge my heart is beating during rowing sessions, but is wildly inaccurate. For the stationary bike it tends to not register anything, then overshoot to ridiculous levels before settling in to reasonable agreement with the HR monitor on the bike.
The sleep logging seemed to stop at 14 days even though I have worn the Sense every night for at least 40 days. I’m not sure I care what my “sleep animal” is anyway – is this intended for children, or what???
My next fitness tracker/smart watch will definitely not be Fitbit. I will miss having 7 or so years of history, but if most of it is bogus, who cares?

Good product . Switched from Apple Watch 8 ( which crashed after 2 yrs of use) and find this so superior in terms of battery life. Features are almost same but this is a improved version for a better price
Jeff Wilson –
Just great
Bryn –
This is a great product. We are very familiar with it, and it works smoothly with the existing Fitbit app on our phones.

Good smart watch, still trying to understand why it does some strange things, like counts steps while I’m sleeping. But all in all it’s fills my needs.
Trish O’Brien –
Fitbit Sense 2 is an excellent product, will sure recommend, i am using this for almost an year and really happy with the purchase.
C. Guernsey –
I ordered this for my husband as he had an issue with AFIB the week before. This is perfect. It monitors everything we need to keep an eye on. He’s not tech savvy at all but he can work with this. It’s easy to program and easy to read. We like it so much I’m buying one for myself.

I got this as a gift for my wife. As an Apple Watch owner, I am impressed with its health tracking capabilities. It holds a charge much longer than my Apple Watch, it is way easier to navigate, looks great, and costs much less! She gets all of the insights I do, in an easier to navigate app that the ihealth. My favorite parts are the exercise recognition and the sleep information. The only advantage of the apple watch is the phone control capabilities, which I never use due to being a pain because of how small it is to type on. Once my Apple Watch gets to the point of replacement, I will definitely be getting a Fitbit instead!

Update to my previous review: Leaving at 5 stars for quality, durability, and features. Battery life seems to be about the same as my old Fitbit HR. Initially, I got about 5 days out of the first couple of charges. Now I’m getting about 3-4. I have no problem with that. I charge my phone more often so I don’t know why I would expect more from my fitness device. How quickly the battery drains seems to be dependent on my level of activity. I just check every day to see how much it’s drained so I don’t get caught out with a dead battery. Haven’t allowed it to go less than 20%.
It does not track steps accurately when I do pool exercises. I manually calculated about 2400 steps during my pool therapy and the tracker only counted a bit over 1900, including steps walking to and from the pool and so forth. All total, there should have been closer to 3000 steps so that’s a pretty big disparity. Frankly, I have not found any fitness tracker to be very accurate with step count during exercise as it depends on how much arm swing is involved.
Previous Review: Received my Fitbit Sense 2 (Mist blue and light gold) a few days ago and I love almost everything about this fitness tracker. The mist blue color is a pale blue-grey. The watch casing is a soft gold color like you might see on a car. It matches the seller’s photo perfectly (on my PC monitor anyway.) I think it’s very pretty, albeit larger than I like in a watch. I have tiny wrists and large watch bands/faces are awkward on me. But, to get the features I wanted, it’s worth getting used to. I don’t care for silicone bands as they don’t breathe but I suppose for a sport watch, it might be the best option. The buckling system was concerning for me because you have to pop the band hole over a pin, then tuck it under on the other side against your wrist. It looked like it would be uncomfortable to clasp it and wear, but I’m happy to say it’s not. Just feels a bit weird to me because it’s bulky for my wrist size.
It was relatively easy to set up. The only difficulty I had was when I logged into my Fitbit app previously associated with my Fitbit Charge HR, it kept asking me to log into my account, but I was already logged in. When I entered my password, it said it was incorrect but it wasn’t. I finally tried using my email PW and got into my account. What was confusing was, the Fitbit logo was at the top next to, “log into your account.” So, buyer be aware, if you have to log into an existing Fitbit account, they want your email address/PW, not Fitbit PW.
The biggest reason I chose this model was for water use. I have to do pool therapy and wanted all my steps and activities to be logged in real-time. I wore it in the pool, hot tub, and shower today and there were no problems with it at all. Just be sure to read all the instructions carefully. You can get more info on the Fitbit website for details on setup, use, and care. The device only came with quick setup instructions in the box.
I haven’t really paid much attention to the sleep tracking as I have a sleep number bed that tracks that. And I haven’t compared it against another heart rate monitor. However, based on the level of activity and how I felt during pool walking and exercises, it seemed like the numbers were relatively accurate.
My favorite feature is the hourly buzz to get moving. It not only buzzes on my wrist to alert me it’s time to move, but after I get up and walk around, it buzzes again to let me know I’ve completed 250 steps (based on my current setup.) This feature is priceless as I sit at a PC all day and forget to move.
Overall, 3 days in, I’m very happy with this purchase and feel that the price was fair compared to similar devices with the same features. It also came with 6 months of free premium app services which I appreciate because it gives me a good amount of time to decide if I want to continue with the premium for a monthly fee. I do not find that app either intuitive or user-friendly and it will take some time for me to get the hang of using it.
Should I run into any problems with my Sense 2 in the future I’ll update this review.
Sherry Lepird –
I have had the watch for over two years and it was worked perfectly
Sydne Betz –
This has worked really well for about 1.5 years. One big issue with Fitbit is the sleep measuring, you have to remain motionless for an hour before it starts counting sleep. And I sleep way too badly for it to measure well.
Battery life was REALLY good until a few weeks ago, almost exactly 2 years after getting it. Battery was lasting about a week. Now I have to charge it so often, it lasts about a day and a half. That’s fine for some people but a way downgrade from what it was. 2 years, must be time for a new one.
C. Guernsey –
After trying out Garmin, Oura, and Apple Watch and returning to Fitbit (previously had the Charge version), I have to honestly admit that Fitbit is the best smartwatch. Starting from battery life, tracking steps and most importantly sleep. There are no hidden charges unlike the competitors. Highly recommend it, btw it also looks great.

I love my watch so much. It’s light and super functional. It’s easy to read. The monitoring sleep function is my favorite. The band is nice. It’s stayed nice and kept in c great condition after daily wear for many months.

After 5 years of good service my old Versa was struggling to keep a charge for 24 hours so I decided to replace it with a Sense 2. Huge mistake!
This device drops to 20% charge in about 12 hours and then requires charging for about 2 hours. You can wear it during the day or at night, but you really can’t do both unless you set aside a couple of hours for charging.
The watch has all sorts of sensors, but they all need to be turned off if you want 12 hours of life. Searching the message boards this seems common. I will play with the recommendations Insee there for a couple more days before returning it, but I’m not hopefull.

This watch is fantastically functional: it does everything a watch should do and costs far less than the Apple watches. The best part is that it goes days without needing to be charged, and charges completely in about 30 minutes. I keep a charging cable in my car and just pop it on while I’m driving. The charging cables are a little funky, but replacements online are inexpensive so when the pins on one die, I just replace it.
The only thing I don’t like is the wrist band that comes with it. Fortunately there are many third party options available so you can choose what you like.
I have mine paired with my iPhone and it does a good job of tracking everything. It even starts tracking for walking and biking automatically when I forget to tell it and recognizes when I’ve stopped. Sleep tracking is also useful – just don’t get the idea that it’s perfect and you should do everything it tells you. Sometimes the “readiness” rating seems suspect.
Still trying to decide whether I like the new AI “Coach”. It gives useful device that matches advice from my trainer, but it’s a little too chatty for my taste and sometimes goes off trying to solve a problem that doesn’t really exist.

Second Sense 2. Great product. I hope battery lasts longer than my last. Got about 3 years before starting to act up.

Overall it seems to be a great watch. I specifically bought this for my mother because she had a stroke and I wanted her to be able to check for a-fib. I also wanted her to be able to monitor her heart rate and oxygen levels.
Ecg- its finicky, you have to really play with the placement of your fingers in order to get it to start reading, then most of the time the results are inconclusive. This part of the watch is supposedly designed by cardiologists and approved for 98.8% accuracy. The process to actually see the ecg graph is unnecessarily difficult. Samsung does a much better job in this category.
The setup is easy, and straightforward. The app is also pretty straightforward and easy to use.
Overall its a pretty standard smartwatch, with a few extra health monitoring related features. If you’re looking for a watch to track a-fib, id probably steer away from this one. Otherwise it seems great.
Kindle Customer –
Does what it says.
Battery lasts a week.
More convenient than the rest, doesn’t need charging every night.
Google screwed it up though.
J.R. –
I purchased this watch primarily for its continuous heart monitoring, ECG app, sleep monitoring, plus some basic fitness like steps and stairs.
It was easy to install. I was pleased to be able to turn off the GPS and Alexa which may have been good for an extra day of battery life. I was able to turn off the fitness nags. I’ve been running and working out over 40 years and don’t need nags. I was also able to skip the Premium service since I don’t want a monthly bill and don’t want other nagging.
There are a huge number of watch faces available. I focused only on free watch faces. One thing that wasn’t clear is that apparently you can only install 6 faces on the watch. When I found a better choice, it wouldn’t install and had no useful explanation of why not. I ended up looking specifically for watch faces that included a battery indicator (surprisingly not universal!) and basic fitness figures. The hard part was finding watch faces that increased the font size of the battery % and fitness figures so they were more easily legible to older eyes.
The biggest problem is with the watch band. I have a narrow wrist and bands with holes like the OEM band are never spaced in a way that fits well. So I ordered a new band that is metal mesh and uses a clamp to fix the length. That works to get a comfortable fit, but is a pain to put on. Good thing I only take the watch off once a day! So I tried another watch band that had a folding clasp, like my old watch band, and is adjusted in length by removing links. The whole process of removing links was a serious pain, requiring a magnifying ring light and great patience. And the link removal did not yield a snug and comfortable fit, just as with the OEM watch band. Back to the band that works, for now.
Update. I just discovered it is possible, apparently, to get an adapter from my old watch band that attaches to the watch with pins to the FitBit clamp system. I’m hoping that will allow me to use my old watch band which was excellent.
Further update:
https://www.amazon.com/dp/B0BN1RVM5W?psc=1&ref=ppx_yo2ov_dt_b_product_details
This adapter took a long time to arrive all the way from China, but it worked perfectly. My old watch band was a 20mm band with adjustable sizing clamp and a folding clasp to take it on and off:
https://www.amazon.com/gp/product/B08CY5D2LB/ref=pe_2313400_740551120_em_1p_0_lm?th=1
Now I have the best of all worlds. A good watch and it is easy to put on and take off with a snug fit. I wonder why no one seems to make this style of watch band specifically to fit the FitBit?
Paula Bond –
Yep, they really need to allow zero stars because that is all this Fitbit model is worthy of! I have owned two prior Fitbit watches that lasted for about five years each. The last one, a Versa 3, stopped monitoring my heart rate and sleep. Since that is extremely important for me right now, I decided to purchase another Fitbit. The Sense 2 seemed to check all of the boxes. So, I ordered one and immediately set it up when it arrived. Or at least I tried to. It would not let me past the big red X on the screen once I had jumped through all the hoops. I boxed it up and sent it back to Amazon for a replacement that arrive within a few days. I set it up, I got one red X after I set it up, but was able to get that to go away after shutting it down and turning it back on again. Didn’t seem to be an issue and the heart rate, oxygen, and sleep monitors worked beautifully. For a while. Then it stopped. Again. Another defective Fitbit.
I was really trying to stay loyal to the brand even though Google has taken them over and I’m saying now that it was not a good move necessarily. I sent that one back and ordered another replacement that just arrived today. The set up went fine. I got another red X, but after shutting it down and turning it back on it went away and everything seemed to be fine. So it seemed anyway. Within an hour, the screen would shut off and the only way I could get it to come back on again was to reboot it. I had to do that three times until I finally said I was done with Fitbit. It is now boxed up. A return label is on the box and I am done with Fitbit. I will never give them another dime of my money!
I know there are good and bad reviews for these watches. I will say that the first two I had were very reliable as long as they ran for the five or six years that they did. In fact, the first one I got was actually one that my sister had been wearing for a few years and she ended up getting an Apple Watch so she gave me her Fitbit charge. I wore it for about four years before I got my versa three. At that point, I actually gave that Fitbit charge to a friend who is still wearing it. I’m starting to think I should’ve held onto that one.
If you’re thinking about this watch, you don’t have to take my advice but I would save yourself the stress and the time of boxing up Returns and look somewhere else.

Does everything it promised and more
looks good big display so I can see it holds up though everything I do and I only take it off for my shower or other water activities
David L. Johnson –
Excellent watch. I got it to replace my Versa 3, so I could have the ecg function which I now need to monitor. Most functions of this new watch are clearly superior to the Versa 3. Trivial to set up, handles phone calls, Alexa, weather, exercises, and health monitoring.

Fitbit Sense 2 is an excellent product, will sure recommend, i am using this for almost an year and really happy with the purchase.
Fantastic amp. Bumped my subs super hard. Used it on 20% power and that was enough for me. Amp lasted around 3 weeks –
I’ve always been into fitness and health. I’ve always wanted to track my steps but didn’t want some dumb looking smart watch on me all the time. BUT. This watch looks expensive and nice like an apple watch. Not to say thats what you’re buying it for but it absolutely doesn’t look stupid. It’s almost like a game every day to see how many steps you can get. I am 6’1 and went from 243 pounds to about 223 pounds in just 3 months. It’s insane. I already had the ability to be in okayish shape but this has changed my life for the better. For 220 dollars this might be the best investment anyone can ever make. Also tracks sleep so you dont have to pay a small fortune for a whoop ring
Enrique –
The screen is blank. It will not start it will not sync. I have followed the recommended actions. Many times. Hold button for 10 to 30 seconds. Hold button for 10 to 30 seconds while charging. Attach and detach charger 3 times in 8 seconds etc while holding button. The Sense 2 will vibrate when expected but does not reset. The watch is a brick now, unusable. don’t buy.

Was good while it lasted but quality wasn’t there. Pieces started falling off the back ( EKG contacts ) after only 2 1/2 years of gentle everyday wear. Stopped working properly shortly after that. Dissapointed at the longevity of this product.

Tried It –
When my original Sense died prematurely, I researched whether to just get another one, or spend an additional $80 to upgrade to Sense 2. I decided not to risk another premature death of a Sense, and went for the new model, expecting everything the Sense did plus new functions. I was unpleasantly surprised that the “look and feel” were so different, for no apparent reason. Specifically, what you see when you swipe in a direction has changed. What was a left swipe is now a down swipe. What was a down swipe is now an up swipe. From a left or right swipe, there are some new tiles with corresponding new functions, which are upgrades, but some (hourly activity this hour, and hours today with at least 250 steps) are gone and not available on the watch, only on the app, a downgrade. After 24 hours with the Sense 2 I am faced with a decision whether to return it and buy a Sense, or keep it. My two star rating reflects my feeling that this product deserves a grade of D.
Updated to add two more negatives: The heart rate is often missing from the clock face. This may be the fault of the face or the device itself, but it’s a fault. I like a statistics heavy face. Two minute quick scan mindfulness sessions are seldom logged, despite repeated refreshes (synchronizations) or quick scans. Only the longer guided sessions are reliably scanned. My decision whether to keep or return the Sense 2 is still pending, awaiting results of functions that require more time.
Five month update: This was prompted by the email reminder that the free introductory six months of Fitbit Premium would auto-renew at the end of the month, for $90 a year, unless I opt out at least a day before expiration. The problems noted above most annoyingly persist. On the other hand, I have come to rely on some of the additional capabilities and health information available only with Premium; and tempted by those I have yet to explore, I have reluctantly and somewhat unhappily decided to continue.
Update, September 1, 2025, after just over 27 months: The battery now lasts less than 48 hours. I wear the watch continuously, including yard work with a gasoline powered trimmer, blower, and mower, and remove it only for charging. Another negative that I forgot mention earlier is the charger that came with it failed long ago, apparently because one of the protruding electrodes no longer protrudes enough to make contact with the watch’s recessed electrode. The aftermarket charger works fine, but I shouldn’t have had to buy it. Otherwise I have come to rely on the watch and the health information it provides. If the battery situation continues to deteriorate, I look into the service contract. If it isn’t covered I will probably, and again somewhat reluctantly, buy another Sense 2, unless there’s a newer better model by then.
Another update, 5/27/2026: This evening Google pushed the new Fitbit app to my iPhone. It doesn’t display most of the data, gray blocks instead. So far, the watch is fine but the app is useless.
Update 7/1/2026: I changed my previous one star to three, equivalent to a grade of C-, after Google finally pushed out the full app and i worked with it a while. The app is heavy with AI coaching that is not always accurate: when I edit a statistic to correct it, the correction doesn’t ripple through all tabs or AI sermons. And the AI often sends premature notifications. One example was when I woke up in the middle of the night, took a sip of water, noticed that my phone just lit up, and opened it to see that I’ve had only 3 hours and 28 minutes of sleep overnight, and the AI has given me all sorts of advice based on the assumption that I was awake and up for the day. The blurb from the AI disappeared when I actually got up several hours later, but only after I forced a refresh several times. There have been a few features that I couldn’t access. One of them, hourly step activity, was eventually made partially available in the app, but actual progress each hour is available only during the final ten minutes of each hour. Another feature that I couldn’t get to was the ECG: the AI’s instructions didn’t work, its Plan B workaround also failed, and when I looked for Plan C the AI gave up and referred me to the website that needed a user ID and password that I’ve forgotten because they haven’t been needed in years. My previous Fitbit Sense and app used to show a little map of the paths I took when logging a walk, but sadly that feature is no longer available. I expect Google to work out the bugs and correct the omission(s?), but it’s hugely disappointing that there are any bugs or omissions at all.

Just great

On the watch itself:
Pros:
– accurate heart rate measures
– smart awake alarms help me get out of bed more easily in the morning over traditional alarms
– screen big enough to see everything but not too bulky in the wrist
Cons:
– pushing a cart or stroller it doesn’t track steps
– GPS connection is not strong sometimes disconnecting in the middle of an exercise and taking a while to reconnect
– vibrates for no reason sometimes as if there was a notification or alert but then nothing is there
– bands do not breath well and irritate my skin causing me to remove my watch more frequently compared to previous Fitbits
– watch face options are limited
The company:
This is my fifth Fitbit watch in seven years, so needless to say Fitbits are not built to last. What kept me to buying the Fitbit instead of switching to another brand was the app had better visibility and was more user friendly than other brands. I used to be a diehard Fitbit fan, but this last year has changed that.
In the last year or so Fitbit has more frequently made changes to the app which remove functionality that you might be using to motivate your fitness goals. At one point my stairs were not visible, Fitbit support said the visibility was removed but the watches were still capable of tracking it so it might come back in a future update, it did after some time, but why remove it in the first place? Another example for the most recent update is removing the daily streak counter. I was only on around 100 days, but there are people online who were looking forward to seeing their 1000th day streak banner but won’t be able to because Fitbit took it away and support told them it’s just not a part of the app anymore. The support team doesn’t decide or implement app changes, but they are rather unsympathetic to frustrated customer when changes occur most likely because they have to listen to the same complaints all day long.
What I have learned is that Fitbit is terrible at guessing which features of the app motivate their customers the most and are rather inconsistent. While the price is more affordable than other brands I will sincerely consider switching brands when I inevitably have to buy an new watch next year. If you have to purchase a new Fitbit every year and a half while other brands consistently last 5+ years, then is the Fitbit truly more affordable in the long run?
In my opinion, if you just want a tracker to check stats on the watch itself and you think it’s a fair price for a watch that will last no more than 2 years, then this is a good option for you. If you plan to rely heavily on the app and would be disappointed if your favorite feature was all of a sudden gone, then I’d recommend looking for a different brand.

The Fitbit Sense 2 has many good features. It tracks steps and workouts, it connects with Google Health to log your sleep quality and other aspects of your health, it has an ECG that works well, and it has a number of helpful features like an alarm, stopwatch, heartbeat monitor, text and call notification and weather. Where it falls short is in the notifications for fast, slow and irregular heartbeat. I bought this watch to alert me for possible AFIB and to take proper steps. I was very disappointed when there was no notification of any sort during a recent episode, so the watch didn’t work as promised. I would go a different direction if this is the reason you are consider the Fitbit Sense 2.

Amazing. One of my favorite purchases I made in a while.
The app is incredible, I have a pixel 9 pro and the Fitbit app was already installed. Upon connecting my sense 2 to it, it functions even better. I love the nutritional aspect and all of the fitness aspects. Makes it super easy to track in and out calories because it’s already done.
I primarily do weightlifting/powerlifting/bodybuilding and I’m currently taking a break due to injuries, and using this for everyday fitness is superb. Can’t wait to see how it is when I’m back in the gym. The sleep stats are phenomenal as well. I already notice my sleep habits changing.
I did notice a few glitchy things, like the weather and sync issues. But these aren’t a problem if you give it proper time to catch up. Meaning, if you check it immediately in the morning (like me) it won’t sync properly. Just give it 20 mins and go about your routine and it will catch up.
Can’t recommend this any more. If you’re thinking about one, just buy it.

My second one. I am very happy with the health info that keeps me going during the day. It tracks my sleep very well and measures my steps as well.
