Japanese Vocabulary is an application for studying Japanese vocabulary. It consists of a set of cards, each with the kanji spelling, kana reading, and the meaning in English (or another language). It uses the Leitner system for managing the cards, which means that you see the cards you know well less often than you see the ones that you don't know very well. This allows the learner to focus on learning those words with which they are having trouble. It comes with the JLPT 2, 3, and 4 vocabulary lists.
