disappointed mapper

This app does amazing stuff. I finally purchased it after friends described it. My only gripe is that it doesn’t support the Apple Watch. Am I the only one who thinks this would be terrific? A tap on the wrist when approaching a waypoint or junction. Or when you wander off the route. Or when your heart rate exceeds a set point. How far to the top of the hill? How steep is this trail I am hiking? So much info to be had without having to hold your phone in your hand.
