Simply put, the higher your HRV, the better. ***Requires Apple Watch with watchOS 10 or later*** HRV Tracker for Watch integrates with the Health app and uses data stored in the Health app. To ensure your Apple Watch can record HRV measurements, open the Health app on your iPhone to check for existing data: Health app > Browse > Heart > Heart Rate Variability.
