Description by Keisuke Nakashima(from the App Store)
Katakana Which helps you learn katakana in a simple, game-like way.

Each round is short and easy to repeat, making the app a good fit for quick study sessions. You can also review the previous question and check weak characters later, so it is easier to reinforce what you missed.
