Harvee: Watch Stress Monitor

Ready for iPhone Duo, Apple Watch Series 12 and Ultra 4! Harvee adapts to any screen and orientation and brings in the new recovery HRV from Health.

Harvee is an HRV-based stress and recovery app for iPhone and Apple Watch. Harvee reads the HRV, heart rate, sleep and activity data your Apple Watch already records in Apple Health. Harvee requires no additional wearable or chest strap. HOW HARVEE ESTIMATES STRESS - Harvee estimates physiological stress from heart rate variability (HRV). - Harvee calculates RMSSD from Apple Watch heartbeat data. On Apple Watch Series 12 and Ultra 4, Harvee uses Apple's Recovery HRV instead. - Harvee compares your daily average HRV with your own 30-day average, not with other people. - Harvee sets your usual HRV range around your 30-day average, using the smaller of one standard deviation or 20% of that average as the range in either direction. - Harvee interprets a daily average below your usual range as higher-than-usual estimated stress, and above it as lower-than-usual. - Harvee needs at least 30 days of HRV data to build your baseline. Until then, Harvee shows your stress level with a notice that it is still learning your baseline.
