One focused loop — learn, review, apply — across the JLPT N5–N1 path. Bilingual, mobile-first, and usable without signup.
Every kanji and word has a review date, stage, and accuracy trail. Difficult items return sooner; mastered items step out of the way.
Kanji, vocabulary, grammar, reading, and mock exams follow the JLPT path from N5 to N1, with relevant vocabulary curated per level.
Meanings exist in English and French. Reviews accept answers in either language so French-speaking learners are first-class.
The app is fully usable in temporary mode. Create an account when you want to save progress across devices and browsers.
