What is Fitbit MobileTrack?

  • Food tracking
  • Weight tracking
  • Setting fitness goals
  • Adding friends
  • Friends leaderboard
  • Cheering, taunting, and messaging friends

How do I get Fitbit MobileTrack?

To get started, download the Fitbit app from the Apple App Store, Google Play Store, or Microsoft Store, and tap Join Fitbit. When asked which tracker you're setting up, choose "No Fitbit Yet?" and follow the MobileTrack instructions.

  1. Log into the Fitbit app and tap the Today tab User-added image > your profile picture.

How does Fitbit MobileTrack track steps?

Low-power step sensors inside your phone track your steps and send the data to the Fitbit app.

How does Fitbit MobileTrack track distance?

Your distance is estimated by your stride length. By default, stride length is calculated using your height and sex. If you feel that your distance estimate isn't accurate, you can adjust your stride length by following the instructions in How do I measure and adjust stride length for my Fitbit device?

How does Fitbit MobileTrack estimate how many calories I've burned?

MobileTrack estimates your number of calories burned based on your BMR (Basal Metabolic Rate), which is calculated using the height, weight, age, and sex information you provided when setting up your Fitbit account. For more information, see How does Fitbit estimate how many calories I've burned?

Does Fitbit MobileTrack work if I'm not logged in to the Fitbit app?

Yes. Once you set up MobileTrack, your phone tracks your steps regardless of whether you're logged into the app. Log in to the app when you want to see your progress.

How long does my phone store data?

Your phone always stores data for the last seven days (including today). If you do not have an internet connection for weeks or even months, your phone will store your data until you connect to the internet and sync your data.

How does my step information get from my phone to the Fitbit app?

When you open the Fitbit app, your phone's data automatically syncs with the app.

Does it make a difference where I wear my phone?

No. Phone manufacturers haven't suggested that the location of the phone affects step count.
