User reviews

Simply the best

This should be a 5 star average. There is none better for tracking your HRV and analyzing ways to improve it. Highly recommend.

Impraticable

Pas en franรงais!

No metric option

An app that aspires to be a benchmark for HRV testing apps and not offering an option for metric distances and weight is disappointing and cheap. Itโ€™s only the US that is behind everyone else, after all!

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
