Live a healthier, more active life with Fitbit, the world’s leading app for tracking all-day activity, workouts, sleep and more. Use the app on its own to track basic activity and runs on your phone, or connect with one of Fitbit’s many activity trackers and the Aria Wi-Fi Smart Scale to get a complete picture of your health—including steps, distance, calories burned, sleep, weight, and more.

TRACK ACTIVITY: Accurately record your steps and distance with MobileTrack when you carry your phone. For all-day tracking of stats like calories burned, active minutes, and sleep, pair the app with a Fitbit tracker.

RUN SMARTER: Enhance runs, walks and hikes by using MobileRun to track your pace, time and distance. You can also control your music, get voice cues and use your phone’s GPS to map your routes. (Continued use of GPS running in the background can dramatically decrease battery life.)

RECORD WORKOUTS: Use your Fitbit tracker to track your exercise, then check the app to see your stats, their impact on your day, and how your performance is improving.

MONITOR HEART RATE: Use a Fitbit tracker with PurePulse™ to analyze heart rate graphs in the app. Identify trends, manage stress and see the results of your workouts. Review resting heart rate trends to see when your fitness is improving.

LOG FOOD FASTER: Easily log calories with our barcode scanner, calorie estimator, and expanded food database of more than 350,000 foods. See your meal history at a glance, and get nutritional insights.

MEASURE HYDRATION: Quickly log your water intake to make sure you’re properly hydrated during workouts and throughout the day.

SET & MANAGE GOALS: Create weight, nutrition and exercise goals, and start a food plan to stay on track. Then get a visual picture of your progress with colorful, easy-to-read charts and graphs.

SEE HOW YOU SLEEP: Set sleep goals in the app, and use a Fitbit tracker to monitor how much time you spent awake, restless or peacefully sleeping.

SHARE & COMPETE: Connect with friends and family by sharing stats, sending direct-messages, and competing on the leaderboard or in Fitbit Challenges.

STAY MOTIVATED: Get a nudge in the right direction with notifications that pop up when you’re close to reaching a goal or have already met one.

SYNC WIRELESSLY: Fitbit trackers sync your stats to computers and 200+ leading devices so you can continuously track your progress without needing to plug in.

MANAGE WEIGHT: Connect wirelessly to the Aria Wi-Fi Smart Scale to seamlessly track your weight, BMI, lean mass and body fat percentages, and to see your weight trends over time.

Customer Reviews

Syncing is slow and they got greedy.

You can by and expensive device to track your sleep, but unless you pay them even more money for another level of service, you won't be able to see the details of that sleep. Just their interpretation for you.

On top of that, the sleep syncing is slow and something is up. In the morning when I turn my sleep of by taping my Fitbit, I sync it. But the first sync does nothing that I can see. The user should be confused at this point if you are designing the app with a basic understanding of user interaction. Then I sync again. It takes forever. In the middle of the sync, I get notification from the health program I'm with and connected my Fitbit account to. THEY got my sleep data, but I'm still just watching a progress bar. Eventually, it's done and I get my data. What is Fitbit doing to prevent me from seeing the bits that just went from my Fitbit to my phone over Bluetooth? And why so painfully slow? I have gigabit Ethernet and 150mbps tested between my phone and router.

Fitbit connection

The Fitbit app is helpful but concerns mentioned from others should be looked into. I have a One and like monitoring during the day. My battery is not holding a charge an is really messing up my step count. There should be, both on the device and in the app the same battery charge lines as when the device is plugged in and charging to let the user know exactly how much battery life is left. Not just the general moderate rating given. I have to plug the device in to the charger to find how much is left. I am now having to charge the device every other day. At the price of the device it should last more than a couple of years. The synching is really poor lately. The app is very helpful and needs all the annotations and monitoring help of a device possible. Thanks for working on the issues.

Commercial Driver Here

I drive for a living and my Charge 2 seems to think I'm walking when I'm stuck in rush hour traffic or just driving slow around shippers and receivers. Be aware of this because Fitbit makes you go online to your dashboard to change the activity type to driving to void out those recorded steps and then you can choose to delete the activity. I'll just have to start taking it off when I'm driving which stinks because I'd like to monitor my HR throughout the day. I wish there was a built in function or a small analog switch that you could flip or tap when you get in a vehicle.
