Thankfully, the developer has fixed the font issue. Version 1.0.2 is definitely worth checking out--as is the Heisig book for which this program is designed to support.

If you are using the Heisig book, this program will definitely be helpful to you. You pick the range of kanji you are studying, and the program generates a flashcard test--in the way Heisig would approve: the program displays the English meaning and you then have X seconds to write your answer (in kanji) on a piece of paper. The program then shows you the correct answer.

Most kanji flashcard programs show the kanji first, and then have the student pick the English meaning. While this is also a useful drill, the Heisig book encourages the opposite approach. According to Heisig, if the student learns how to write the kanji character, the reverse process--how to recognize the kanji character--is free. Once trained to generate the kanji, the brain handles the reverse process automatically.
