Stayfitt receives workout data from Google Fit (for Android) and Apple Health (for iPhone) trackers pre-installed on your smartphone. To share workout data connect the Strava app to your Google Fit or Apple Health trackers. When sync is set up, Strava transfers data about all your activities, except for the number of steps when you walk. Workouts and activities from Google Fit and Apple Health are synced and downloaded with every login to Stayfitt.
