Polar H7. Which Android app exports to excel?

I just bought a Polar H7 belt as it seemed to be compatible with many free apps.

I would like to monitor my HRV and export these data to Excel to merge them with other data and make statistical analyses.

Do anybody know an Android app in which export to Excel is possible?

Thanks a lot.

https://play.google.com/store/apps/details?id=com.hrvxt records all the relevant HRV parameters and exports to Excel, if you don’t mind spending $20. There is also a free version without export, for testing.

Does the Elite HRV app allow for export? What about the default Polar H7 app?
