Choosing a Provider

Best for comprehensive health data: Fitbit — covers the widest range of daily metrics including body composition and intraday heart rate.

Best for athletes and training load: WHOOP — deep recovery, strain, and HRV metrics designed for performance athletes.

Best for GPS sports tracking: Strava or Garmin — detailed workout events with route data, splits, and multi-sport support.

Best for real-time sync: Garmin — push-based webhook delivery means data arrives in VitaSync immediately without waiting for the next polling cycle.

Best for quick setup: Fitbit, WHOOP, or Strava — all use standard OAuth 2.0 and are available via self-service developer portals. Garmin requires manual approval.
