Historic Data Backfill

When a user connects a personal Garmin Connect account with Fitrockr, a historic data backfill of 85 days will be automatically initiated. 

Contact Fitrockr Support if you need more than 85 days of historic data to be backfilled.


To synchronize the Garmin device, user needs to open the Garmin Connect app which will then automatically fetch data from the device. This data is automatically sent immediately to Fitrockr in the background.

Background Synchronization

Garmin Connect app does not synchronize in the background. A sync requires the user to open the Garmin Connect app which will initialize the sync.
