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.

Awesome one!

I keep searching one product which could work as a watch for just telling me time so that I don't need to bring out my iPhone during walk or run or exercise, as well as track my health daily data. For these two major features requirement in mind, I keep waiting for apple watch for a while. However, after I try it in store, I do not like it. It doesn't look like one product deserve 400 to 700 dollars, it has too many over fantastic functions I actually do not need for a watch at all (e.g. Video watch; we chat app), and most importantly it will annoy that charging it every 18 hours. Then one of my best friend recommended Fitbit to me. It is exactly what I want, simply design, longer time without need for charging, track your health data even during your sleep. Especially for me, I do not like wear too much on my arm, so Fitbit is perfect for me so I don't need to wear a sport band and a watch together. In addition, the Fitbit app on iPhone is clean and well organized. Highly recommended!

Unreliable of late

I have used Fitbit since December 2013 and always praised its effectiveness in promoting regular exercise and counting calories. It has its weaknesses but once I got used to it, it became impossible to not check my progress everyday. But recently, especially starting 2015, the updates have been extremely rocky. It had worked fine before but after an update there would be tone of problems. The biggest problem of late is its inability to sync which is annoying! Before, it was able to sync and give me my progress immediately as soon as I open the App but now it will sync at random times, couple of times a week. Because of its randomness, I cannot suss out what the problems is. Only way to know my progress now is to meet my step goal since the device will vibrate, but even then.. it won't sync. I just hope they can fix it as I am (or used to be?) a big fan of Fitbit.. It helped me lose weight so I'm grateful but unless it's fixed, this device is useless.

This app is great!

It's more realistic than other apps I have had. It lets me pick and choose how much weight I want to lose, how fast I want to lose it. It even let's me just choose how many calories I want in a day. I love that it also helps you track your water intake (I am HORRIBLE at drinking as much water as I should) and this app helps so much! I can't wait to get an actual Fitbit to sync it up and get fit! The only downside I have is when I am at a restaurant it doesn't connect to the app so I can choose "subway" or wherever I am, you have to manually type it in and search for certain things. I think it should have a list of restaurants and have their menus for you to chose from, that would just top the cake! I recommend this app HIGHLY!
