The most clean, effective and important app you can download as an endurance athlete. This app will single-handedly eliminate the chance you keel over after 20 years of endurance training.

The best app for measuring HRV, simple yet powerful. I used it everyday to track my improvement. Thank you developers for helping us in our journeys to better lives and well-being.
