Arccos uses a variety of your smartphone’s features to precisely detect your shots and location. The app requires access to the phone’s microphone in order to hear the sound of the impact between the club and the golf ball. This is one of the key ways we detect your shot.
Location services uses your phone's GPS signal to track your movement on the golf course and place your shots in the appropriate spot.
Note: Arccos 360 will not work without the phone in your front pocket
