The Power of HRV Data comes up more and more.
For Sleep as android this would be the possibility to get a deeper look on the quality of sleep.
Once you integrated the option to use Heart Rate Monitor like Polar H7 just a wile ago, there where much more options.
Just record the R-R intervall Data from the Hear Rate Belt and put a CSV File per Night to the database or export to cloud space.
The User can Analyse the Data for them selve via Kubios.
Start analyse the data direct from the app. Build a Graph for the RMSSD oder PN50% ratio during Sleep.
implement graphical Pictures for FFt, histogramm, tachogramm etc.
put an option to view the Stress grafik during night via Baevsky.
This would show many people a way to get much more sleep improvement, because they know there Stesslevel during night.
