Kana Flip was the first app of Andres that I used. I needed to learn hiragana, and it taught it to me very quickly.
Kanji Flip is the program I now use after feeling confident in my ability to read kana.
The amount of extra info in Kanji flip is going to keep me busy for a while. I am learning the meanings and some readings for now, but the two example words give me a sense of context. True, some of the words are too hard for me, but it gives me something to shoot for.
I have now also gotten Japanese Flip, now that I have gotten through JLPT 4 in Kanji Flip. These have been solid study aids for me. I emailed Andre and he responded very quickly. I get the impression he cares about what he puts out. Keep up the great work!
