Now the calculator can register nine-hole courses, and thus nine-hole scores, and use them together with eighteen-hole courses and scores to calculate your handicap index. Also, you may choose in Settings whether to display your handicap index as a nine-hole or eighteen-hole index. It also displays your differentials as 9 or 18-hole values according to your preference. And you separately choose whether to predict your score for nine or eighteen.
The lock screen problem is fixed.
