Replacing your Fitbit Device

It is VERY important if you purchase a new Tracker to replace your existing Tracker that you do not create a new Fitbit account in the process. During the device setup, please be sure to select EXISTING USER and login with your active Fitbit credentials. 

To register a new device to your existing account:

Fitbit Mobile App:

1. From the Fitbit app dashboard, tap or click the Account icon.
2. Tap Set Up a Device.
3. Choose your tracker and follow the onscreen instructions to continue.
