Attention: This app only works if you have an Apple Watch Series 3 or later.

The Apple Watch 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.

If you want to measure a new value, use the Breath App from Apple.

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.
This HRV app provides a way to analyze the HRV SDNN values ​​recorded by the Apple Watch.

Researchers at the University of Zaragoza in Spain have shown that the values ​​recorded by the Apple Watch during a session with the Breath app are very accurate. Comparable with professional chest straps.

To filter your own HRV data, this app offers the possibility to display only those HRV values ​​that are recorded during such a session.

To get to most out of your data it is important that you measure always in the same situation. For example: "First thing in the morning" before getting up.

Works well

Supports iOS 14 and Watch Series 6. Wish I could filter by type of reading on the Watch app but still lets me see the info on the go without my phone. Thank you.
