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.

    I'm in the developer preview program and using Denim. I couldn't sync my Fitbit Charge using this app. It always searches for a "tracker" with no luck. I use my iPad to sync, very disappointing... Btw, settings on this app always persists. For example if I set my daily step goal to 12k using iPad or web dashboard and open this app, app sets it back to 10k.

    Would absolutely love to see the call notifications come to windows phone 8.1 update 1. I'm using a Lumia 1520 and I would love for my fit it charge hr to tell me who is calling and when. Always being in meetings means the phone e is on silent alot. A vibrating watch would help a lot. Also, it would be great to get a better understanding of my sleep. I feel like I get terrible sleep. 18x restless.... What does that mean?

    "Tap to get started" wont go away and app crashes on Facebook connect. Good app in general, but do you guys even test before you release?

    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!
