Most kanji apps show you a character and its readings and expect you to memorize them cold. Kanji Study takes a different approach: you learn kanji through the vocabulary words they appear in. By studying real JLPT words, over 5,000 of them across N5 to N1, you absorb kanji readings naturally, one word at a time, the way they actually appear in Japanese. What makes it different: Vocabulary-first learning: master readings through words, not rote memorization Writing lessons with stroke detection: learn correct stroke order and get instant feedback Spaced repetition reviews: English → Japanese and Japanese → English, including writing quizzes Full JLPT coverage: structured levels from N5 through N1 Audio pronunciation: hear every word read aloud Works offline: no internet connection required Ideal for JLPT test prep, Japanese language students, or anyone preparing to live or work in Japan.
