It works well. It would be nice if you could input the +X numbers before the point numbers, since that's normally the order that you tally them when playing. If I have to just remember the hand bonus until after I've counted my card points, it's easy enough to just add them in my head before I put them into the app. Kinda defeats the idea of having those +X buttons. Also I would prefer it if you could see the points per hand stats on the main screen as you go instead of having to long press a person's score. I'd rather see that than a photo of the box cover. Still, props for building an app for this obscure game.
Resolved minor issues.
