Hole19 Premium offers 'Auto-change Hole'. This feature detects whenever you are moving to the next hole and automatically updates to the hole in which you currently are.
After starting a round, to enable the Auto-Change Hole: tap the bottom bar > 'Settings' > Turn the 'Auto-change hole' toggle'On'.
NOTE - This feature is specially developed for the smartphone, which means that when you use an Apple Watch, it's the iPhone that commands the watch to change holes. You should make sure to keep both devices within a 10-yard range to avoid pairing disruption.
