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.

App needs improvement

I absolutely love my Fitbit, but the app needs to get on the level of its competitors. The calorie tracking part is subpar, the meal options are really limited and makes it hard for me to accurately input my calorie intake. I constantly have to go back to myfitnesspal and look up an item then take the dietary information and input it into the calorie tracker. I would just track my calories in myfitnesspal but I want to keep everything in one place. The sleep tracker needs some work too. I expected that it would go more in depth like all other sleep monitoring apps. It just tells you when you're restless and awake, and doesn't track when you're in REM or not. I'm disappointed that I still have to use a handful of apps when I was expecting to replace them all with the Fitbit app.

Won't sync

I got a flex last summer and used it religiously. However, in the past few months, the app has stopped syncing my device. Sometimes it does, but usually it doesn't. I can get it to sync about once every two days. Compared to previously when I synced over 10 times a day, that's pretty frustrating. I can't check my sleep pattern, my step or calorie progress, and updating my silent alarms is a gamble, since they many not sync, so my device might not wake me up. I've seen others having the same problem in other reviews, so I hope fitbit will take notice and fix this soon. As of now, the app is worthless to me and I've all but stopped using my fitbit because of it.

Love love love!

This little device is comfortable. I don't use jewelry or watches so I was skeptical but I forget I'm wearing it all the time. I love the syncing with my IPhone it is the best thing I have purchased for my health. It keeps me always wanting to beat my previous day's steps and workouts. I have already lost 2 lbs and have only owned it for a week. 10 more to go! It keeps me accountable and encouraged.
