If you use an Apple Watch paired with your iPhone, GPS distances on Apple Watch are based on the actual location of the iPhone to which it's paired. Make sure that both devices are within a 10-yard range to avoid pairing disruption.
However, you can use the internal GPS of your watch. All you need to do is turning the Bluetooth 'Off' - after starting the round using Simple Input on the iPhone - and the watch will use its own GPS showing you distances to the Front, Center, and Back of the Green. Note that you will need to turn off the Bluetooth directly on the iPhone Settings, otherwise, if you simply turn off the Bluetooth on the Control Center, the watch will keep fetching the iPhone's GPS. Go to your iPhone Settings > Bluetooth > Switch the toggle off.
At the end of the round, turn the Bluetooth ON again to reestablish the connection between both devices. Given that the Watch will not be connected to your iPhone, please note that if you decide to input scores via the Watch they will not be synced to your phone while you don't re-enable the Bluetooth connection. Make sure that your Apple Watch is charged fully before going out to play.
- It is not possible to create standalone apps for Apple Watch. Every watch app requires a counterpart iPhone application. As soon as Apple introduces standalone watch apps, we might consider developing one;
- Starting a round on the watch: currently, we are not considering the possibility of starting a round on the watch (it's definitely not a good user experience);
- GPS on the watch: as far as we know, it is not possible to force using the GPS on the watch without turning off the connection between the phone and watch.
