Audio/Haptic feedback is a sensory feature on your watch that provides a cue that your automatic shot was tracked successfully. You might hear a noise or gentle tap after the tracked shot if both this feature and Auto Shot Tracking are turned on in your Wearable section of Golfshot settings.
On the Golfshot app go to Account Settings (top right cog on home screen) > Wearables > If 'Auto Shot Tracking' is ON, you have the option to toggle 'Haptic Feedback' OFF or ON.
