20 Life
20 Life is a beautifully minimalist app that does what it promises, but it needs iPhone 5 support. Also, using 2 fingers to count up can sometimes be a bit unreliable. Buttons should be an option, but not required. Support for more than 2 players would also be nice.
EDIT: The app has been updated with iPhone 5 support and buttons! You can also "roll" once you start a game. Thanks for listening, devs. Review changed to 5 stars.
