Just what I needed!
This app is great for learning Hiragana and Katakana, best out of the 10 or so I downloaded!
My only gripe is that it would have been nice to have a flashcards/quiz section which was more customizable, allowing you to manually select particular characters giving you trouble, or allowing you to study all Hiragana/Katakana at once, instead of limiting you to twenty preselected characters.
Still, a minor issue, and a great and helpful app overall.
