The repetition algorithm appears to just throw cards at random. This is unreasonable. Please consider more intelligent question selection.

Would be great using kana instead of romaji and added notified status bar when program is running for allowing after switching between program.

I would love to be able to shuffle them.

Mark (*****)
Stellar. Far better than my old hand-written flash cards, which only taught me to recognize my handwriting.

Drobak (*****)
Very good app! Would love the option to make custom lessons with the kanji I struggle with. Recommend! But what's up with the wi and we kana? Fake?

Anthony (*****)
Excellent app. Great for quick practice any time.

great app. using it daily on the tube.

Works great but I'd like to create my own kanji card sets, eg ones I have trouble with.

Magnificent! The only thing I'm missing is more kanji. Seriously one of the best apps available- paid or not!
