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 and runs, 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 iPhone 5s, 6, and 6 Plus. 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.

ELEVATE YOUR TRAINING: Track stats and routes for runs, hikes, and walks with MobileRun. See your pace, splits, time, distance and route maps in real time. Record workouts and use the monthly exercise calendar to follow your training program. (Continued use of GPS running in the background can dramatically decrease battery life.)

LOG FOOD: Easily log calories with a credible food database. Use our barcode scanner or use the quick calorie estimator for customized entries.

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 iPhone 4S and later 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.

New and love it, so far!

I am new to Fitbit. Bought the Charger HR which started my experience with the app. It took a little getting use to, but once I figured out how everything was integrated I liked it even more. I will say I think there are some errors/bugs in the app (usually in my favor), but it is still a great motivational tool. I like it so much I bought the Aria scale that tracks my weight, body fat and BMI, this should help as my "second opinion” to what the app is telling me. Something I find very helpful in this app is the tracking of the food I eat, This really helps me see what I have been doing and how it is helping me change my eating as I become more aware as to what I was doing. This more than anything helps me to be honest with myself, but also shows how it affects everything else. Thanks Fitbit.

Needs Cycling Mode

Overall I'd say this is a solid app, but it desperately needs a cycling mode built into the app. I have the Charge HR, and it's nearly pointless for cycling (being that it has no GPS - I also understand that the Surge model does have GPS, but not the point).

I suggest an update for Charge HR owners. Why not allow proper cycling to be recorded from your phone, using your phone's GPS, while gathering heart rate data from the Charge HR? Sure, Fitbit would like to sell me a Surge, but I like the physical profile of the Charge HR better, and I believe GPS locks much faster and more accurately from an iPhone. I know I could just select "Run" or "Hike" from the app, but then everything is labeled wrong, and it still counts steps even though you're biking.

Fitbit, please update this app to include a proper cycling mode for non-surge owners, specifically optimized for that range of motion.

-Record GPS data from app (ave speed, max speed, pace, distance)

-Put Charge HR in activity mode (gather accurate heart rate data, show updates on the Fitbit display at intervals, and disable the step count)

Otherwise I will have to use Endomondo for my Cycling data, and just accept that my steps will be way off that day. At that point steps are more of a score than an accurate measure. Please add this in an update! This should be pretty simple!

Please fix!!

I switched to Fitbit from Jawbone about 7 months ago and have loved it so much have bought several of them to give as gifts. I live by my Fitbit and the results it shows me up until this last version update for the bracelet. It is so frustrating to give it all you have in a workout to open you app to show it only logging half of the active minutes and my BPM incorrect - since this update most of the day it doesn't even track my BPM the screen has a --- on it (in both app and bracelet). I have waited a week before this post to see if would be corrected based off all the other concerns and it hasn't :( up till now this has been amazing but if it doesn't get fixed soon I will have to find something else that gives accurate information....I have several friends with Fitbit and everyone is having the same issues. Please please fix!
