📝 About this app
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.

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
