Fitbit is messing up regularly these days
I got a Versa 4 Fitbit about 3 years ago by signing up for the NIH "All of Us"
Program. First year of the App was free. I wear my FitBit all the time and use it to track steps and log my sleep, which has been problematic for me as I've gotten older.
I don't keep the app open but do my best to log in every day or two to make sure the data from the device gets transferred to the app. Lately it is totally failing to record my sleep, which is incredibly frustrating. I am wondering why I'm bothering to pay $80/year for something so bad. It still seems to track my steps but I wonder if it's accurate-? All in all, since Google bought out Fitbit, I am having trouble and question if it's worth the hassle and cost.
Also, with the RFK Jr at the helm of HHS, I doubt most of those wonderful scientists at NIH who developed the All of Us program are even still there, and suspect if the program is continuing, that the data might be used for nefarious purposes thanks to theft of data by DOGE and Palintir criminals.

Couldn’t Sync Sense 2!
My Sense 2 couldn’t sync since May 7th 2026, even after updating the newest version of Fitbit app.
I used Fitbit for almost 15 years, I don’t understand every single bug happened with any product lines.
After Fitbit cut its community features, I lost my Fitbit friends from all over the world, which is extremely disappointing! And now I couldn’t even sync data. I don’t know why I don’t switch to another brand!

Battery Problem
I think my battery is going bad! My Fitbit shows a smiley face and then freezes. Then when I get it to respond again, the battery level goes from 75% to 10 % within a few minutes.
Logging Food.
Difficult to add food to app to track calories. The Back arrow on top of screen causes the app to lock up.
So terrible
I can’t find the right words to describe how awful the app and the Fitbit devices are. I’ve had about three so far. first one tapped out pretty quick and I had to send it in for a new one. The new one had battery issues from the start. Also waiting for 20 minutes to sync. now my third one not worth even a 10th of what I paid for it. If it’s not battery issues, it’s how many times do I have to swipe just to see my heart rate? can’t find a clock face to just show me heart rate when I tilt the screen. It’s literally no use to me. I have to take it off and just put it in a drawer now. I can’t spend my entire run tapping on my screen. I’m trying to sync it afterwards forget it. I don’t wanna go through waiting to sync every day, so I wait maybe once a week. Gotta find something else to do, multitask, while it syncs. completely worthless.
Just download my info!
Super annoying that it can take hours to get info off of this. Or that sometimes it just doesn’t work (o2 sensor, or sleep recording) I have only had this for 6 mos
Not working properly
Calories not showing on dashboard. Last couple of weeks the total calories were adding up correctly when entering food items for macros. So frustrating.
Mal producto
No lo recomiendo, quizás quieren que les compres un reloj cada 6 meses para que puedas tener los privilegios de seguir tus datos personales. Lastima pero sus mediocres relojes así con ese servicio nunca lograrán superar a los pioneros.
Ni siquiera te permiten publicar lo que uno piensa de ellos. Si

Eh
Got it to loosely track sleep. It’s doesn’t want to sync for hours after you wake up. If you enter your time manually (because it took so long you didn’t think it would sync) it will convert them to tracked hours, and double your sleep duration in the tracking. You can’t delete one for some reason. Seems like a pretty easy flaw to fix. I wouldn’t recommend paying for the app and just using the free settings.
Making the review worse than before. It takes all day for it to sync. Not worth the $80 for the watch.

Can't change watch face or apps
I cannot update my watch face or watch apps from the app. Whenever I click either button, a white page appears with an infinite loading circle and the back button disappears. I have tried restarting my watch, restarting the app, updating the app, deleting the app and reinstalling it, and nothing works. I am beyond annoyed. For such an expensive device you'd think the app would at least work
Food serving sizes ruined
This app used to be great, but all these useless “fixes” just screw everything up. Logging food is completely worthless now as the serving sizes are all messed up and will randomly change even after you logged food! Horrible app!
Basic Math Incorrect
This app gets basic distance math incorrect-there is clearly an error between daily and hourly totals, and daily goals. In multiple ways it is off by the conversion from miles to km, and after years this blatant issue is still not fixed.
It’s something so obviously wrong it makes you wonder if they are doing any basic testing or critical thinking about their app, and even despite years of complaints, this very basic accounting is still incorrect for many people, e.g. if a goal is set to 3 miles it will show as 1.86 miles in some screens and 4.8 miles in others, which is off by the mile-km conversion factor in different directions.
The summation of hourly distance totals also doesn’t equal the stated daily distance totals, again off by the mile-km conversion factor.
I don’t know how to trust anything this app does if BASIC unit conversions are so blatantly incorrect.
It will also do stuff like say “No data” for something until you click on that thing and move the calendar around a bit.
Very buggy overall, hard to trust anything, clearly there is stuff wrong that should be so obvious with any amount of testing or thought it makes anything in the app untrustworthy.

Can’t turn off daily goals
If you search on net, lots of people dislike the feature, but Fitbit, in its wisdom , will not allow you to dismiss it.
Terrible
This app is the most buggy mess I have ever had. What did google do? It’s becoming impossible to use. Deletes food entries as you’re entering them. When they do take, it double triple quadruples them. Awful, just awful.
Garbage not capable of writing to apple health
Absolute nonsense app cant even sync with apple health.
Can’t log food
Can not log food. It won’t load. I restarted my app, restarted my phone. Redownload the app and you still not can log food. do not download this app it’s worthless.
Continued problems entering Nutrition
You clam to have fixed bugs and other issues but the nutrition info continues to be a mess. It gets deleted and then info reappears 3-4 times. Everyday I have to manually delete duplicates. Why can’t you fix this?!?!?
Unsyncs every day
I might as well not even track my steps at this point.
App doesn’t work
To work correctly you have to force quit the app every time or most metrics won’t sync. Also, dismiss a message and it comes back each time. Been dismissing a message for past 12+ days and it won’t go away
Malisima
Compré el versa 4 y cada que actualiza la version y se conecta con mi celular se queda congelado mientras no se bloquea la pantalla el reloj funciona una vez que se deje de usar ya no sirve de nada y tengo que Vuelvo a formatear
No More Sleep Tracking & Doesn’t Sync on new iPhone
I moved to a new phone and now there is no more sleep tracking. Nobody can assist me. They said they will contact me with their “higher tier” 5 weeks ago, but they didn’t…. I have to move back to my old iPhone 12 to track sleep with my Charge 6 🫣
Even on the old phone it can’t add up my sleep hours. If I wake up to pee? Those 3 hours are not included in my sleep summary. Grrrr… it worked better years ago

Dumping my Fitbit versa 4
I don’t want premium and you are insisting on payment
Not Working
The app is not syncing and the update never works. Very frustrating!
Nothing works correctly
Ever since I changed my app to Google the calories in vs calories out graph is not correct. And when I click on learn more links it takes me to the Google phone app to
Purchase phones. I hate this new fit bit. The Google phone purchase links are a huge turn off.

Not happy
Doesn’t stay sync with my versa3.
Share device not work
There is feature
In app, that I can share device. So I choose “People using this Scale”, then Invite user. Go to email, tap “Accept invite”. After we both see users in app. But when invited user trying to use scales, it’s shows - “Device wasn’t setup correctly, you cannot sinc data from this scales for this account, try to Reset device or ask for invite. So I did it 5 times, and from other phone and vice versa. Same. Fix it guys, it’s sad, that nobody cannot sinc it in family. This failure make this scales just mediocre scales. Aria Air device.

Glitch in system
App use to work beautifully in the past but lately it’s been glitching I’ll put in my food intake for the day sometimes it doesn’t want to
Load it. The an hour later I’ll see about 7,000 calories worth of food because the system just doubles the amount of food I put in my daily
Tracker this has never happened before not sure what is the issue with the app. It seems like a glitch something that needs to be addressed by IT department. Thanks for the help!

You’re not buying this. It’s a rental.
Less than three years old and won’t charge or power on. Customer support is chat only. Went through it several times. Promised updates that never happened. Did not track sleep or steps accurate by times of day. Andy in support was rude and dismissive. Pretty steep price for a piece of junk.
Pérdida de conexión bluetooth
Se pierde constantemente la conexión bluetooth con el reloj versa 3. Cada momento lo tengo que emparejar. Por favor, corrijan este error. Además de esto, no recibo las notificaciones de WhatsApp ni me aparecen en la lista de apps en notificaciones, a pesar de mandar un mensaje por primera vez
Recent firmware update killed my Versa 4
After the recent Firmware version: 61.20001.220.31 for Versa 4 my watched which used to hold battery for 4-5 days started to die within 6 hours and now it’s completely dead. Can’t sync it anymore. Factory reset didn’t work. Reached out on Fitbit forum but no response. It’s a very sad end to my 10yr relationship with Fitbit.
Public preview
The last update made the ai coach almost unusable. It can no longer generate exercise plans with specific workouts and frequently displays error messages when asked a question. This was looking very promising, but the last update makes it no more useful then the free app.
Data logging stopped working on Aria 2
In my household two devices using Fitbit and Aria 2 scale stopped working when this version was released. Daily login report needs to happen.
Fitbit versus 2
I have had nothing but problems since google has been involved. Won't stay synced. Glitches with data. WiFi connection issues 😡🤬 absolute nightmare
Stop It!
Making me keep the app open on my phone drains the battery & serves no purpose - it does not synch properly! My Fitbit will say one number of steps while the app says another. It also has problems keeping the hourly activity count accurate. And activity goals for someone my age are outrageously high. Also noticed recently my heart rate was over 250 bpm when I was seated/resting. Took my pulse myself & it was 72.
Can’t update
Two days ago… I was asked to try a new layout with the option to go back to the old one. Today, I’m required to update to the new one but you can’t update the main page… so all that I see is my sleep info. I don’t need to see that all day. The metrics page to edit gives you nothing to change or save.
Can’t provide a consistent step count
It was annoying enough with the prior app version(s) when step count totals fluctuated as much as 150 throughout the day (other metric totals also fluctuate throughout the day). Now, with the new version, I have seen the total change by more than 400 steps (increasing and decreasing) - while I am sitting down. Given that the app can’t provide a consistent step count I don’t know how I’m supposed to trust any of the other metrics that it supposedly tracks. If this continues, the next fitness watch I purchase will not be a Fitbit. Which is unfortunate as I have been using fitbits for more than a decade now. But you know what they say….change is good. I prefer to be loyal to companies that provide a reliable and consistent product but with so many other trackers out there I believe it may be time for a change.
Poor application
Fitbit 5 failed to meet expectations
Day 4 of writing a review that will get deleted.
Ever since Google took over, this app is not great.
The notifications don’t go from your phone and the tracking when walking is horrible.
Stop erasing the review and fix this GOOGLE

Strange Update
Updated the app and the AI Coach has been removed, what happened here?
Scale user
The scale is not sending my weight to the app. It doesn’t seen to be connecting to Bluetooth or WiFi.
Leaves something to be desired
My sleep isn’t tracked properly; I have to manually enter my exercise and food and water so not sure what is the benefit of this product. 😢
Sync is currently broken...
The watch (Versa 3) is no longer syncing when the app says it has. Weather doesn't update, and Google Calendar event notifications do not get sent. It's been months. Just wish the Pixel Watch had a comparable battery life. Who wants to charge their watch every 20 hours of non-use? Might as well just go back to analog. And yes, I've tried uninstalling, signing out, unpairing, etc. I feel like the Fitbit is being sunsetted, but with minor updates to keep up with App Store policies.
Exercise Crashes App
When I start an exercise activity about 20% of the time the app with crash and I cannot restart or log anything. I have to reinstall to fix it and it’s frustrating.
Became very slow
Crashes all the time, became very slow. I reached the customer support and all they could advise was to restart the app. Nothing happened. It’s a shame , cause I use this app for several years and it was never so bad.
Calorie bugs
I can’t update to the latest version due to compatibility, and there are now bugs in the calorie tracker. Food entries are doubling randomly, and total count is not showing on main page. It is taking a lot of refreshes to compute the total properly.
Garbage
This app has so many bugs even with the updated bug fixing Band-Aid. It will not log food properly. It will not log your steps properly. You have to constantly refresh it even restart your phone to try and get it to clear. I would not purchase the yearly subscription. It’s not worth it until they fix it for real.
Constant glitches
I used to love this app, and I appreciate that the barcode scanner isn’t free to use and not behind a paywall, however, the glitching has been getting so bad it’s almost not useable anymore and unfortunately the recent update hasn’t helped.
Cardio Load recommendations dangerous
The cardio load recommendations are crazy and dangerous. I swam for over an hour - 72% of the time vigorous and 27% peak and it tells me I still need to exercise more that day to meet cardio load.
Edits
The newest update has not stopped whatever bug irritating it. In the food section my items keep multiplying and when you add another item it mysteriously deletes itself and when you attempt to re-add the item completes the same rhythm. Please correct this, it’s throwing my calories off.
