Description

Heart Rate Variability (HRV) measurements recorded by your Apple Watch can provide insight into the stress your body is experiencing. By using HRV Tracker to track short-term readings and long-term trends, you can see how factors such as daily workload, workouts, and sleep affect your body's readiness, recovery, and stress. 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. In addition to automatic recordings, you can also use the Mindfulness app on your Apple Watch to capture new HRV data. Start a Breathe session, and once it ends, a new HRV measurement will appear in HRV Tracker.

***How Is It Measured?***
HRV Tracker uses heart rate variability measurements calculated by detecting the variation between individual heartbeats. Your Apple Watch automatically measures HRV in the background and stores it in HealthKit. HealthKit uses SDNN (Standard Deviation of NN intervals), which reflects the standard deviation of time between normal heartbeats (measured in milliseconds).

Please note that many of the features mentioned above are available only to subscribers.
