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.

Great Way To Keep Active

Ever since I have had my Fitbit Alta (July 2016) I've never been so competitive with others to see how far I can walk! I think it's great, a great way to remind you to get moving. The only issue I find is there is not enough variety on the exercises to add. I'm a fitness instructor and teach Les Mills classes and feel these classes should be added on as the classes are becoming forever more popular and it would be great to have a better track of activity at the end of the day! Apart from that, I love my Fitbit!

Good, But Major Bugs

Many good features, but a few frustrations:
If you start tracking a run, the system will sometimes report poor gps. But it stops tracking the run until you press continue on the warning. As I'm using an arm band when I press start, I run and don't see the warning so don't track my run.

You can't adjust the volume of the app when in the app. The volume control controls the ringer not the app volume for running cues. So if you had the volume down, you have to switch to another app like your browser, turn the volume up and then switch back to the Fitbit app.

Needed to restart Fitbit after recent update

Needed to reboot my Fitbit after recent update as would not sync with phone. Went through the help section on app but found solution in forums instead. I've got a One and had to hold down button until rebooted. Having had a Jabra Up and a Nike band. I'm not sure why everyone raves so much about Fitbit. Frustrated that it doesn't fully integrate with Apple Health app like my Jabra did. Dashboard could be more informative. Just ok. Could do better Fitbit!
