Great app. Keeps score well. A couple of glitches though: a score of 180 is counted in stats under 100+ and 140+ and 180+. And it should be in the latter category only; a score of 140 is counted as 1 under 100+ and 140+ and should be in the latter only, and so on. I ran one (artificial!) nine darter, hit stats, and had 3 100+, 3 140+ and 2 180+.
The 180+ category should be 180 (without +).
It would be nice to have a 170+ category too.
And it would be nice to have the number of sets and legs won shown better.
If that is fixed 5 stars. Love the ability to play against computer, and very easy handling.
