Nightly Recharge Insights
Polar's Nightly Recharge is a unique recovery metric that combines your autonomic nervous system (ANS) status with sleep quality. Vitalstat syncs this data and presents it alongside your other recovery metrics — like HRV from Apple Watch or Body Battery from Garmin — giving you a comprehensive view of your recovery from multiple data sources.
