Tired of using a chalk or marker board to keep score during your '01 game? This app will keep score and save stats for your games of '01 from 1 to 4 players. Play your game of choice, 101 up to 1001. You can also set a custom score to practice checkouts. Set the number of "legs" and "sets" to play a match with a friend with alternating start. Averages and stats for each player are viewable during and after game play. This app is great for match play as well as single player practice.
