HRV (Heart Rate Variability)
Definition
The variation in the time between consecutive heartbeats, measured in milliseconds. Higher HRV generally indicates better autonomic nervous system balance and recovery; lower HRV can signal stress, fatigue, or under-recovery. Premium fitness wearables (WHOOP, Oura, Garmin, Apple Watch Series 6+) measure HRV continuously.
How MoveTogether uses it.
MoveTogether does not score competitions on HRV. HRV depends heavily on individual physiology, sleep, training history, and stress — comparing HRVs across people doesn't produce a meaningful leaderboard. We score on activity output (calories, minutes, steps, workouts), which is fair to compare across users.
Your HRV stays in your wearable's app (WHOOP, Oura, Garmin Connect, Health on iPhone) where it belongs. MoveTogether reads only the activity metrics relevant to scoring competitions.
