I have the hiragana and katakana apps from these guys both are very good and worth the download. Catchy songs and good pronunciations help memorize the characters and vocabulary. Only thing you need to be careful with is taking your time while writing; it tends to accept touches as full strokes sometimes and that throws off any who are seriously trying to learn. Great for kids and adults and great for students who have a rushed curriculum like most college students. Worth the download.
