It would be good to see this somehow tie in with HRV - heart rate variability. I've been tracking mine daily for 6 years, now. Can recommend kubios app on phone and their desktop software is stunning, too. There are other apps i use - hrv4, for example and there are others. I prefer kubios as it is minimal and to the point. Https://intervals.icu (sports/ body performance analysis) may be another place to show this.
