Live a healthier, more active life with Fitbit, the top app for tracking all-day activity, workouts and health.

Use this app on its own to track basic activity, or connect with Fitbit’s line of activity trackers and the Aria Smart Scale to get a complete picture of your daily stats—including steps, distance, calories burned, sleep, weight, and more.


TRACK ALL-DAY ACTIVITY: Track your daily steps and distance right on your smartphone with MobileTrack for supported Lumia devices. MobileTrack accurately tracks your basic activity when you carry your phone. For more in-depth, all day tracking of stats like calories burned, active minutes, and sleep, pair the app with a Fitbit tracker.

LOG FOOD: Easily log calories with a credible food database. 

CORTANA BETA (US, UK and AU Only): Using Cortana and a custom Fitbit voice experience, log foods and set alarms with simple natural sentences.  

ACHIEVE YOUR GOALS: Set goals, enter your weight, record your sleep and start a food plan. Then view your progress and track your trends with easy-to-read charts and graphs. 

COMPETE WITH FRIENDS: Enlist friends and family to help you reach your goals by sharing stats, joining fitness challenges, direct-messaging each other, and competing on leaderboards.

SYNC WIRELESSLY: Fitbit trackers continuously sync your stats with your Windows Phone to give you real-time access to your progress without plugging in.

OUTSMART YOUR WEIGHT: Connect wirelessly to the Aria Wi-Fi Smart Scale to seamlessly track your weight, activity and more.

Fitbit requires Windows Phone 8.1. Lumia devices need to be running the Lumia Cyan firmware.

    Everything works great except for this one thing : Your sleep does not sync over the Bluetooth connection. If you want to look at your sleep patterns - which I do - you have to do it manually. Aka it renders sleep mode pointless.

    All day sync doesn't work. When syncing is finished I get a flood of notifications that are all exactly the same. Usually about 14 within a few seconds. This occurs any time I achieve a goal, or are near achieving the daily goal.

    Love the app and the syncing ability, but when I had to switch back to my lumia 520 it won't download - keeps saying "Attention required". I have no issues downloading other apps, just this one (and have more than enough space). Also - synching requires a cellular data connection - would be nice if you could sync with a WiFi connection...

    Nicely done. Works well with Charge HR. But pls Fitbit, get Caller ID working on Charge like you do with iOS and Android.
  • by Jacob 1/25/2015
    Great app, syncs well with my charge, but how come this app doesn't have the run route mapping feature that the iOS and Android versions has? Most WPs DO have GPS hardware, you know. Are there any plans to bring it to the WP app soon? I have a NL 1520, the best WP you can get other than the HTC One M8, yet when it comes to Fitbit features, a Galaxy S3 has more, simply because the Android app itself can do more. Please consider bringing your WP app on par feature-wise with your other apps, as there's much to be desired that everybody else already has. Again though, what it does have is really great.

    Can't sync Bluetooth from my Flex to my HTC 8XT. Running Windows 8.1.
  • by David 1/24/2015
    Works well in keeping info from my Charge HR but never syncs in the background. When I start the app I get a notification that background syncing has stopped.

    not good enough,lacking some function like call display.
  • by Brian 1/24/2015
    Great app but sync'ing does not work reliably on the fitbit Charge HR and Lumia Icon w/8.1 DP. I restart the fitbit and phone, it will sync once then subsequent attempts to sync its looking for "Looking for tracker".

    Absolutely love my Fit bit! Can't figure out caller id though.
