Health

I take the Hrv 4 training measurement daily to monitor health status. I appreciate the feedback with the results and guidance regarding the intensity for the day

Asking for a refund right now

Apps is hard to use, even linking with apple watch, this is probably fitting foe someone who loves to take a manual measurement everyday at the same time, someone who is deep into this sort of metrics, but for someone like they are probably better off with something else rather an apps on a phone, in short too complex and manual for an everyday person and fall way short for a pro

VERY GOOD

It would be great if the app could send a notification every morning, im struggling with my consistence because some mornings i forget to use it.

How to do measurements with newer cameras??! BUYER BEWARE: glitchy

Cool idea but the camera measurement thing seems to work quite poorly with my newer model iPhone. It’s nearly impossible to keep BOTH lenses plus the flash covered for the duration. I would not have purchased the app had I known. Any tips now that the cats out of the bag for this sucker

The Gold standard

Marco’s HRV app and academic research are leading the field for many years now. The app is easy to use and set up and my daily companion. I can only recommend it.
