A widget is like an App extension that offers you quick and concise information without having to open the App.
To use the Hole19 Widget you'll have to add it to your list. Swipe left on the lock page or home screen to check your widgets list. There you will see an 'Edit' button, tap to open the 'Add Widgets' screen and then tap the green '+' icon near the Hole19 logo and 'Done' (top right).
Now that you have Hole19 on your widgets you are ready to start a round.
During a round, Hole19 Widget will show you the green distances. You can tap 'Show More' to see hole 'Notes', use the 'Distance Tracker', 'Input Scores' or 'Finish' the round.
