This app is a little too complicated for my taste. The info shown for any given day is a little overwhelming. Id prefer something simple like an average resting heart rate, wake up rate, and average workout rate. Also the average resting heart rate seems to be the average of all readings between 55-79, instead of all readings where you were actually resting, so it is always around 66
