Need to support Apple Health- Steps

Please make a link for step counts so they sync with the phones Apple Health app. That way I can run with the phone in pocket. Thank you. Excellent app. Works

Useful for initial setup

The app makes setting up the watch much easier. The route tracking, waypoint / location recorder and step counter are all too basic to be useful.

The step counter is over counting. So it would be helpful if there were additional calibration options. I’ve tried adjusting my height profile which helped a little, but it would be easier to just directly enter a stride distance.

Needs to be able to add friends

Love my pro trek watch with the step counter but they need a way to join groups or add friends on the step counter. This is the only reason Casio pro trek is not my everyday watch
