Aim. Tap the course to set your line. Drag to look around the hole, scroll or use + / − to zoom.
Swing. Press Lock the line, then stop the meter. Stop just under 100 in the pure band for a clean strike that rolls out much further. Past 100 you overswing and pull it offline.
Putt. Land inside the putting rings and the putts are automatic: inner ring 1 putt, outer ring 2, anywhere else on the green 3.
