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.

    Since I upgraded to 8.1 it struggles to sync. Unistalled and installed it twice, still doesn't work

    It's pretty good so far. Would be nice though I the battery indicator just didn't say full or half full. It would be better I it was in quarters because the tracker just died this morning. Other than that its pretty accurate.

    Force won't sync with Lumia Icon

    Great app, great to not need PC (& dongle that shouldn't be needed anyway) to sync. Only issue is sync blocks phone from connecting to other BT like my car because its always on instead of connecting just T sync then disconnecting, so had to disable background syncing. Even with manual sync, after closing this app I need to turn BT off & back on so my car can connect later. Surprising to see one feature (the one feature that makes the app worth installing) suck so bad when the rest of the app is pretty good.

    Purchased the Surge as part of the early release only to find out that it cannot be setup via the Windows Phone app... disappointing. ***Update*** Fitbit mobile development team has reached out to let me know that that it expects to update the app next week to add support for the Surge on Windows Phone. I hope this includeds support for Caller ID + Text Notifications.

    Great App

    Well designed app. Works perfectly for syncing and tracking sleep, calories, and activities. I really cannot complain about my Charge. Some users have said caller I will not work on Windows phone and this is true. I think it has more to do with Microsoft locking down the OS than Fitbit. Unlike on Android and Apple, we do have voice support, meaning we can simply tell it what we ate and it'll track it for us through the app. The only reason why I removed one star was because on the Android and Apple version, the app is able to expand the steps and sleep graphs to show times. I would love this feature for Windows Phone. This works on the PC, but the phone is still missing this. C'mon Fitbit, we can do this! :)

    Not user friendly very confusing does not work. Website is terrible! I got free with phone. I would never recommend buy this it's going in a drawer.

    Just Awesome. You can set your goals, add food/activity/water quick and easy, add a fitbit device or run it with only an account, they even employed cortana to use voice commands, and you have a 'contact customer support' button. That was the kicker for me. Problems? Just click here and talk to us. Beautiful. All I could want more is different ways of viewing the progress graphs.
