Live a healthier, more active life with Fitbit, the world’s leading app for tracking all-day activity, workouts, sleep and more. Use the app on its own to track basic activity and runs on your phone, or connect with one of Fitbit’s many activity trackers and the Aria Wi-Fi Smart Scale to get a complete picture of your health—including steps, distance, calories burned, sleep, weight, and more.

TRACK ACTIVITY: Accurately record your steps and distance with MobileTrack when you carry your phone. For all-day tracking of stats like calories burned, active minutes, and sleep, pair the app with a Fitbit tracker.

RUN SMARTER: Enhance runs, walks and hikes by using MobileRun to track your pace, time and distance. You can also control your music, get voice cues and use your phone’s GPS to map your routes. (Continued use of GPS running in the background can dramatically decrease battery life.)

RECORD WORKOUTS: Use your Fitbit tracker to track your exercise, then check the app to see your stats, their impact on your day, and how your performance is improving.

MONITOR HEART RATE: Use a Fitbit tracker with PurePulse™ to analyze heart rate graphs in the app. Identify trends, manage stress and see the results of your workouts. Review resting heart rate trends to see when your fitness is improving.

LOG FOOD FASTER: Easily log calories with our barcode scanner, calorie estimator, and expanded food database of more than 350,000 foods. See your meal history at a glance, and get nutritional insights.

MEASURE HYDRATION: Quickly log your water intake to make sure you’re properly hydrated during workouts and throughout the day.

SET & MANAGE GOALS: Create weight, nutrition and exercise goals, and start a food plan to stay on track. Then get a visual picture of your progress with colorful, easy-to-read charts and graphs.

SEE HOW YOU SLEEP: Set sleep goals in the app, and use a Fitbit tracker to monitor how much time you spent awake, restless or peacefully sleeping.

SHARE & COMPETE: Connect with friends and family by sharing stats, sending direct-messages, and competing on the leaderboard or in Fitbit Challenges.

STAY MOTIVATED: Get a nudge in the right direction with notifications that pop up when you’re close to reaching a goal or have already met one.

SYNC WIRELESSLY: Fitbit trackers sync your stats to computers and 200+ leading devices so you can continuously track your progress without needing to plug in.

MANAGE WEIGHT: Connect wirelessly to the Aria Wi-Fi Smart Scale to seamlessly track your weight, BMI, lean mass and body fat percentages, and to see your weight trends over time.

Latest update freezes up the app
Chrissypooh82 on 4/21/2018
I don’t know why but ever since the last update 2 days ago, the app keeps freezing on me and I have to close it out constantly. Very frustrating
New update again, broke notifications once more
Mmjdallas on 4/21/2018
I absolutely will not buy another fitbit. I’ve had them for years and they were reliable, but not anymore! Get some decent developers who don’t mess with the product in production!!
lisa loopner on 4/21/2018
Flex 2. Didn’t update the update to the “new” interface/dashboard from 2017 until about a week ago. Now that I updated it, wished that I didn’t. iPhone app freezes while iPad didn’t. I don’t remember having to be connected to WiFi with older dashboard, it’s a pain when WiFi isn’t around to check dashboard. Disappointed.
Update 04-218-2018
Leahkg719 on 4/21/2018
This newest update keeps crashing and won’t fully sync all sections like sleep and heart rate sections. Tried removing and downloaded again. Still not working properly on my Apple iPhone 6
Won’t recognize Bluetooth
ajfox1986 on 4/21/2018
Every time you guys update the app it forgets my Fitbit Blaze and never recognizes when my Bluetooth is actually on! Tried all of the “fixes” none of them work. Please fix this terrible app!
ltlwormgc10 on 4/21/2018
Not getting notifications on my Fitbit after the last update!!!!
Great product, useless app!
Devilishcamaro on 4/21/2018
Everything was fine until the most recent updates. Now it freezes, shuts down, and/or gives inaccurate information. Please fix!
App update
deer hunter28 on 4/21/2018
Fitbit update doesn’t sync well. Seems only some of the stats work well. Heart rate and exercise time erratic. Was better before update.
probably doesn’t deserve 2 stars
myreasonsmile on 4/21/2018
No longer shows sleep info unless you open the sleep panel. I shouldn’t need to do extra things just to see how many hours I got. This app gets worse and worse. It probably doesn’t deserve even 2 stars if it can’t do basic things.
Frustrated lately
WRP3 on 4/21/2018
I have enjoyed this app until the update 3weeks ago. Since then my fitbit will not sync correctly, it keeps trying to locate my fitbit. I have restarted my Fitbit and my phone app to no avail. I’ve emailed customer service asking for help- I have received no response. I’m usually quite satisfied with this app, please get a proper fix as this has become frustrating.
Update not working
patty parz on 4/20/2018
Loved Fitbit all and ionic watch till I just ran latest app update. Keeps saying “searching” when I ask it to update on app (after updating in App Store). Suggestions? I’ve updated my phone to latest OS, rebooted twice, and exited Fitbit app twice and reopened. Still says “searching”
Newest update
ali.t04 on 4/20/2018
I just got the newest update and the app glitches every 15 seconds so I can’t do anything on the app
New Version is Buggy
courtneyide on 4/20/2018
I'm so frustrated! I love my FitBit but with the new version of the app, I am unable to sync and log my steps! It freezes and is extremely disappointing and frustrating. I expected more from the company.
Love the product but the app is too glitchy
Rando194$2 on 4/20/2018
I’ve had my Fitbit since January. The product itself has worked great. Up until a few weeks ago, I didn’t have any problems with it. The app has suddenly become too buggy. It keeps freezing up, restarting, deleting steps, and getting stuck in one screen. Even when I close the app and reopen it, it comes up still stuck on the same screen. I don’t know what you did to it, but it didn’t work and made the app even worse. Please fix it.
Bad Update
vwright29 on 4/20/2018
This app was working perfectly yesterday, updated this morning and it immediately crashes. Please fix!
Fix please
BarrettSpice on 4/20/2018
The app has been freezing ever since the update. Can we please have a fix?!
Please update
FallenRae on 4/20/2018
My Fitbit Ionic won't send text/reminder notifications or calibrate with the last two updates. Meaning my steps and exercise is inaccurate. Please fix this asap. It's basically just a watch right now. We need a new update.
Freezes and closes every time
03.isa on 4/20/2018
It doesn’t take 10 seconds before this app begins to freeze, eventually it just closes all together, I’ve restarted the app and my phone. I’ve even removed the app and re-downloaded it with no luck
Rare to see a poorly developed app in iOS
KRONK MAD !!! on 4/20/2018
... so I took a screenshot. Awesome tracker, very poor app. Thought it would do better on iOS vs Android lol. I say keep the engineers, fire the Fit Bit app developers. Been fighting the same Bluetooth battle for two years. Are we about done with this beta version? Please tell me this is the beta. P.S. “Blaze isn’t syncing because you’re Bluetooth isn’t turned on.” —-in red letters just under the active BT icon. Nice.
New update forces quit on 4/20/2018
New update (4/20/18) will not allow for sync. Crashes every time.
Xcalak on 4/20/2018
Update freezes
Still buggy
LMLee49 on 4/20/2018
It’s not totally accurate and nobody should expect it to be, but it provides some idea of how one is doing. Since it’s required for use with a Fitbit device, it should work without a hitch. Unfortunately with every update, it seems less reliable. Although “connected,” I have to delete the app and reload it every so often to get it to sync… like now. Fortunately no data is lost. Still minus one star.
App freezes since new update
Coorul on 4/20/2018
I have an iPhone 6s. I can’t get the app to work except for just 30 seconds. Then it freezes. But I have had it for a year. Works great before now
New Update
BB8-08 on 4/20/2018
New update is causing my Fitbit to get stuck while syncing unless I restart my phone. Hoping a new update is pushed soon. This is a frustrating issue for an otherwise good app.
OhhBradd on 4/20/2018
App was working great until recently - now it freezes and doesn’t track my Fitbit data. Very annoyed please fix
Chelbeat on 4/20/2018
I have been loving my Fitbit app and I use it every day. However, after the update yesterday, I experience a lot of crashing on the app. It will just freeze up and refuse to do anything. I have to close the whole application.
App works worse after update
GM of 4 on 4/20/2018
Tracking of my heart rate and the daily exercise tacking horrible. The exercise tracking completely drops days as if not completed but other areas show that daily goal met. Not happy.
Not working
Marie210 on 4/20/2018
Please fix it!
Works great when it syncs properly...
Amber Secola on 4/20/2018
I keep having periods of a week or more randomly that refuse to sync. So I just have massive gaps of 0s. NOT helpful for trying to track steps, which is my primary use of this app. I have tried uninstalling, resyncing repeatedly, even creating a new account. I’ve been having this problem for a year now and no bug fixes have addressed it. My steps are all in my Health app but somehow can’t make it to the Fitbit app? I don’t understand.
This app doesn’t work for me
CoonHound43 on 4/20/2018
This app doesn’t work for me no matter what I do. I use my iPhone 6 Plus to do it but after logging in I got my name, password, email, and my last name in it then when I tried to log in it said that my email AND password were not correct but I know that I did it correctly. This is why I don’t like this app and that I would not suggest it to you.
Mediocre at its best
Colddarkwind on 4/20/2018
Paired with Charge 2. Very poor at detecting stairs climbed. Wildly inaccurate resting heart rate. Thinks You are sleeping when setting at your desk. Overall a slightly amusing toy but don’t count on it for accuracy.
Fix it
Pinterestlover01346790258 on 4/20/2018
Takes forever to load. Unreliable
Refuse to sync with AppleHealth.
piersonrife on 4/20/2018
Despite customers commenting and asking for the ability to communicate directly with AppleHealth, they still insist that Apple doesn’t allow them to.
Won’t Sync.
Crazymahomiegirl on 4/20/2018
My Fitbit Blaze won’t sync with my phone. They only way I can get it to sync is if I remove it then add it back. I changed some of the settings and it won’t sync on mine. Ever since the update. It wouldn’t sync.
jlTech00 on 4/19/2018
The new update has a bug that stops you from doing anything even scrolling up and down
App not working
Mkrogers on 4/19/2018
Since the update yesterday my app isn’t working. It just keeps spinning trying to load then shuts down. What can I do to make it work?
From amazing To crap in less than 6 months
BeijingPod on 4/19/2018
This was an incredible purchase for me. I bought the Alta HR six less than months ago. It tracked everything with precision. Now it tracks nothing. I have to manually log everything, and it’s not even accurate. The heart rate monitor barely shows up and when it does it’s way off. What a waste of money. If the app and watch can’t talk to each other’s then the watch is useless.
App cannot even be opened
Xx_LeafyIsHere_xX on 4/19/2018
Ridiculous, I can’t even get on the app because the screen freezes when it syncs with my Fitbit. I could program this app better than any of these developers combined, that’s how bad it is
Great but
SavageGamerGirl on 4/19/2018
Fitbit is helpful to me, but whenever I go on the app to try to set an alarm, it always freezes and takes so long!!! It didn't happen before! Please fix
New update glitched the app
Hekadosjsnakalakdjf on 4/19/2018
I wish this didn't auto update. My app no longer works. It starts syncing but freezes instead :(.
App is glitchy
Ifunnyh8ter on 4/19/2018
Don’t get me wrong I love my Fitbit and the app but after the new update that got released yesterday the app has really been glitchy and needs to be fixed once the app becomes less glitchy I will raise my rating to 5 stars cuz I really do love my Fitbit and the app
CLarissa<3<307 on 4/19/2018
The Fitbit HR encourages you to keep moving!!
Love you but fix your app!!
Alexa verroi on 4/19/2018
I’m such a fan of Fitbit. Love the company, products and customer service. I recently bought the versa and was so excited to get apps and get set up but the versa section is so disappointing! I would of happily downloaded another app instead of dealing with a laggy, buggy experience. I hope you get it together Fitbit.
App crashes
Sarahjcuti on 4/19/2018
My app has worked perfectly until tonight. For some reason it crashes, doesn’t sinc, and just keeps freezing. I close it out and open it back up. Still doesn’t work. I uninstalled the app and reinstalled. Still crashes. I’m really sad about it because I used the app regularly. Hopefully there’s an easy fix.
Fitbit flight
xndjshlsgdosjddhdkdk on 4/19/2018
Just give us Fitbit flight
glitchy845 on 4/19/2018
This app glitches all the time! I always have to close and reopen.
What's up with sync?
SEL in CLE on 4/19/2018
UPDATE: as with every iOS update, the app and my device no longer sync. Why????? Completely useless for me to wear the device if I can’t track progress. Hope it doesn’t take 2 weeks to resolve like the last iOS update in February... UPDATE: there was an app update 5 days ago and wouldn’t you know, my Flex 2 has not been able to sync with the app in 5 days! Very frustrating. I want to remain loyal but I shouldn’t experience these issues with every app update. Anyone else having sync issues? Are developers working on a fix? ————————————- I have a Flex and have generally been happy with it and the app since I started using it last year. Over the last few days the app has decided it no longer wants to sync with my device. I tried charging, waiting, removing/reattaching the device within the app and removing/reinstalling the app. My device is fully charged. Nothing works. Is this a known issue that will be resolved (quickly, I hope!)? Update: I attempted to contact customer support via the app and that no longer seems to work - my message didn't send and I received a "sorry" message. I think the most recent fixes triggered something else... at this point the device and app are useless if they won't sync.
Fitbit Versa
EB 👍😃😀 on 4/19/2018
I got the new Fitbit versa! The versa is amazing. It tracks all the features who need from steps to notifications to Connected GPS. I personally do not need GPS but the Ionic is a great option for people who want that. The notifications are really handy. The design is amazing! Their are not many apps but the apps on my Apple Watch are not very good. I do think weather is a useful app. It is a great Fitbit. The battery life only seems to be getting 2 Days but that is still the best on the market. You can charge it during showers or other times. You can bring a battery pack! Still better than the Charge 2. Much better than the Charge 2!!
Kkrriissmmiilleerr on 4/19/2018
I really enjoy my Fitbit. Love that it’s water proof and I use it all the time. If I had one thing I wish it would do is tell the time. I know this particular fit but didn’t have a face to tell the time. It’s great it notifies me when I ha e a call or text. I can set alarms and adjust my goal all while it gives me reminders to keep moving. If you could have a way for it to tell time I have a suggestion. I work with deaf blind individuals and you could use their watch in a similar fashion to have the Fitbit flex 2 tell time. For example. We have 5 indicator lights. Let’s say it’s 10:15 am The top light( which usually flashes green) could flash blue for AM and pink for PM. The second light could be for the hour so it would flash 10 times. The third lid will have to count in tens. So for 15 it would flash once. The fourth light would flash the ones. So for 15 it would flash 5 times. Pink-AM 2nd light- 10 flashes/buzzes 3rd light- 1 flash/buzz 4th light - 5 flashes/buzzes Time is 10:15 am Just a suggestion.
Recent update has cause my Fitbit to not show all notifications
Tjp83 on 4/19/2018
The recent update has caused my Fitbit to not show texts or calendar events. It will show incoming calls
