Description
The Apple Watch Series 3 is measuring your HRV Data and writes it to Healthkit.
This app connects with Apple’s Health app to displays the recorded data on a Watch App, a complication and your phone.
There are some discussions if this data is reliable and meaningful. So i did't do some interpretation of the data. You can just check the raw values. On the iPhone you can also see your training data in relation to HSV Data.
If you want to measure a new value, use the Breath App from Apple.
I added a 7-day average and a baseline that is an average of the last 60-days.
Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the variation in the beat-to-beat interval.
