Great for learning Japanese!

This is my favourite app on the iPhone, AND the best program for memorizing kanji Ive ever tried on any platform.

You can start with kana, then move on to each grade of kanji in the JLPT. Not multiple choice, so you learn to really remember the correct answer instead of just recognizing it from a list. It trickles in new untested kanji at the rate youre memorizing existing ones, so you eventually learn them all but arent overwhelmed even if you start knowing nothing.

Features that would be nice in future versions:
- Reverse testing (i.e., show the english translation, guess the kanji)
- Ability to create sets & share them online (for class kanji lists)
- More stats: (total number of kanji quized in this set, most-wrongly-answered kanji, etc)

Also check out Japanese Flip, which is the same thing except for vocab.
