My app is mainly used by crossfitters, the HR display from my app is wrong, but HR displays from the garmin default activity seems better.
The current HR I display is the HR sent by activity info, so what can I do?
I have an external chest strap HR sensor, and HR are reliable in all circonstances.
The built-in sensor is less reliable ok, but why a difference between Garmin activity and Connect Iq app? is there a preprocessing?
What I am supposed to answer to users about the HR reliability?
