Grey NguyenTo add to this, currently Apple calculates Max HR based on running, walking, and hiking. It does not consider HIIT in its calculation. Furthermore, Apple updates Max HR on the 1st of the month; however, doesn’t display this in Apple Health (you would check Apple Fitness settings on the watch). I would like to see Bevel not only display Max HR in the Biology section, but also calculate a Max HR using HR data available for all my workouts synced into Bevel (including HIIT).

This was not available before the update but we can add it!
