Wizard Keeper of Score for Android
You cannot scrap a game in the middle and get to another game. It completely freezes to the point you have to uninstall it. It also doesn't let you go back or forth or change anything. It's a shame. It's nicely designed.
Great help, but no undo function. This can be burdensome ;)

Useful since erasable marker no longer works. There is a small problem though: I cannot start a game with just 2 players, I always need at least a third player, even if blank.
