KanjiFlash

KanjiFlash is a Japanese study app built around repetition, recognition, and fast practice. Learn hiragana, katakana, Grade 1-6 Kyōiku kanji, and core vocabulary through flash cards, quizzes, visual study tools, and mini-games.
Start with illustrated cards and readings, then build toward pure character recognition. Mark favorites, track progress, review weak cards, create your own custom decks, and practice in multiple game modes designed to keep kanji study active instead of passive.
