This app is confusing and inconsistent. There are so many other options. I wanted to try test something new. Not worth it. Train hard my friends!

DO NOT BUY! If you have IPhone 17 or higher and they don’t tell you Not suitable for iPhone 17 🥺

You should update info on the app description that it’s not suitable for iPhone 17 pro max I want a refund?
EEstherosk

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.
Ttmazzone

Impraticable

Pas en français!
GBGaëtan STIKER alias Bouda

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. It’s only the US that is behind everyone else, after all!
