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.

    Was working well until yesterdays update. Now although I can add food in on the app, it doesn't show up and it appears to have lost some of my plan information. Please fix!

    Brilliant full-featured app on the Windows Phone platform. I'm glad that I'm able to sync and log items manually rather than just view stats.

    Very poor performance,will not load at all anymore,started off so well.cannot say I'm surprised yet another company coming out with a poor implementation of their app on WindowsPhone.shame really.

    I'm very happy about the app. Works great with my 920 and Cyan. The only issue I have is that my phone stays connected to my fitbit all day long and that the battery of my fitbit gets empty in less then 2 days. How can I disable this? But I don't want to turn of the Bluetooth of my phone. Thank you
