How do I pair Fitbit and Garmin as my Activity Tracker to the Challenge App?
Fitbit and Garmin
Select Fitbit or Garmin on the Select Tracker page. Enter your username and password for your Fitbit / Garmin account and accept the sharing of your step data via the secure Oauth framework. Once that is setup, your step data will be transferred from the Fitbit / Garmin cloud to the Challenge app when you click Tap to sync steps on the Summary Page in the Challenge App.
