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 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.

    I've noticed some details or edits can be entered here, but not on the web and vice versa. Would like some consistency there, but otherwise a GREAT app to have, especially if you are monitoring your calories in/out throughout the day. As of 10.29.2014, I noticed the last update does not chart my food based on my diet settings, just in v. out - why did that suddenly change?

    Thanks a lot for supporting Motion Data on Lumia devices. I may eventually get Fitbit wrist band. In a day view, please allow horizontal swipe to go to next or previous days.

    Restarted and now back to normal. Wish I didn't have to kill the connection manually to save battery.

    Works great. Sync works after update. Love this app, I got the fitbit after I found this app and its a great little health tracker.

    The update seems to have fixed one annoying issue where the app wouldn't start on Lumia 635. The background sync seems to work fine. Excellent update! Love my Fitbit One. I've been waiting forever for this app to come to Windows Phone. Finally not tied up to iPad or desktop. I'm sure a small number of minor issues will be fixed soon, not worth taking a star off for those.
