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.

    Thanks for making an official app. Needs automatic synchronization and NFC support added. Loving updates. Still needs NFC support to launch app when you tap flex band with phone.

    The app worked great on my Lumia 822, but when I switched to a Lumia Icon I'm having issues syncing the band to my new phone. It still syncs at some points on it's own, but not when I manually try.

    The app was working great until last update on 2/25. Doesn't sync with my Fitbit device and is not saving the data I enter. Regarding the fitbit device itself, not very satisfied. I believe it is not accurate and after doing a workout class it doesn't log those minutes as active minutes. I'm glad I got it for free with my new Lumia. I'd be very upset if I paid for it.

    App will not Sync with the Charge on my HTC One M8 for Windows at all. I'm stuck using my iPhone for my daily use since my fitbit is a big part of my life. Everyone in my family has a fitbit. I've deleted the app and reset my Fitbit at least 10 times and still nothing I have been thinking about changing over to the Up or something else that is better supported on windows since it seems Fitbit doesnt really care about WP users

    I am so happy to see that I can now sync my fitbit one with my windows phone now! Thank you for doing such a good job developing the app too!

    Dear costumers of USA in UK if you by a Lumia phone you get free fitbit .. They used to get Bluetooth speakers too and 20 to 40£ voucher and wireless charger Here nothing well I'm done and uninstalling this app just wanted to let you know how much we are disrespected
  • by Fahad 2/27/2015
    Love this app since it tracks my steps, water, food, exercise, and calories burned...but logging into Fitbit on the desktop destroyed all my data. Even though you have to make a profile to use the app, it wasn't backed up onto the servers and when my dashboard eventually synced to my mobile app, everything was overwritten. Smh, guys.

    Awesome!!! Well designed. Works flawlessly with my fitbit flex. Really well thought out and implemented.

    In the beginning, I probably would have given this app a 2 (due to syncing and notification issues). However, the last round of updates fixed both of those. My charge hr now syncs all day, and (more importantly) my phone is no longer spammed by a zillion notifications. The only additional comment I have is more for fitbit than the app: I'd really like to see the food database expanded.
