If you use an Apple Watch paired with your phone, GPS distances on Apple Watch are based on the actual location of the iPhone to which it's paired.
However, we offer a 'standalone' version for Apple Watch. All you need to do is turning the Bluetooth 'Off', and the watch will use its own GPS showing you distance to the Front, Center, and Back of the Green. This will allow you to use the watch's internal GPS.
At the end of the round, you'll need to turn the Bluetooth ON again to reestablish the connection between both devices, to save your scores.
Note: We recommend staying within 10 yards of your iPhone to avoid pairing disruption.
