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.

  • Frustrated lately

    By WRP3
    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

    By patty parz
    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

    By ali.t04
    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

    By courtneyide
    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

    By Rando194$2
    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

    By vwright29
    This app was working perfectly yesterday, updated this morning and it immediately crashes. Please fix!
  • Fix please

    By BarrettSpice
    The app has been freezing ever since the update. Can we please have a fix?!
  • Please update

    By FallenRae
    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

    By 03.isa
    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

    By KRONK MAD !!!
    ... 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.
