I just purchased the Heart Monitor+HRV app and can get HRV data. It shows about 84, which is considered pretty good for my age.
And this is what prompted my question here: Has anyone compared the readings from the Heart Monitor+HRV app to something like Elite HRV with a strap?
I am curious about the accuracy of the Heart Monitor+HRV app in combination with the optical HR sensor on the Venu, and how it compares to other methods of measuring HRV.
