It's an amazing app just from playing with. Super simple. Just doesn't have a calculator type function... Otherwise great app.
With its fully customizable features, this is easily the best scoring app.
Looks extremely good, but very basic in functionality. It is frustrating to adjust scores by large margins: there are no +/-5 or +/-10 buttons, no "increase by arbitrary amount" button and animation doesn't allow to tap + and - signs rapidly (tap doesn't do anything until animation ends) which leads to painful process of counting and tapping the buttons slowly.
