I love this app…nothing more to say. 😊

Excellent app for monitoring heart rate variability. No ads and feature rich. Highly recommended.

Life changing in so many ways…if you want to improve your overall health and wellbeing….do the research and get this app and get started.

An effective tool for making sense and understanding trends of your HRV.

In my mid 60’s, completely out of shape, but looking to get back into it. This is one of the best technologies I have found to help me determine my workouts.

Can’t believe it’s free. This app is amazing. I’m a sports doctor who is currently looking into ways to look after my patients. It’s exactly what I have been looking for!
