Step 1: Hole19 for Apple Watch requires watchOS3.
On your iPhone, please update your Hole19 App to the latest version. To do this, simply go to the App Store, search for Hole19 and Update. Open Hole19 on your iPhone:
Choose the course where you want to play > Tap 'Start Round' on the course profile > Set your Round Setup and please make sure you have the Advanced Input toggle Off and the GPS Mode On > Tap 'Play' at the bottom to start your game.
Step 2: Make sure to have the Bluetooth On > Open Hole19 on your Apple Watch. The round should start immediately.
Step 3: You can easily change the hole by swiping up and down on your Apple Watch screen. Hole19 shows you GPS distances to the Front, Center and Back of the Green. To add your scores and track your Putting, Fairways Hit and Greens in Regulation stats, just swipe left to bring the input screen. Once you're done, swipe again and tap Next Hole.
Step 4: Finish and save your round. You can finish your round on the Apple Watch but will need to save it on your iPhone. Take the chance to say something and share with your Hole19 buddies. You can also share your round on facebook or twitter if you select that option on 'Also post on:'.
