Why it works
- Every glance is a lesson. Widgets on your home and lock screen show one word, kanji or grammar point — no app-opening required.
- Science-based memory. A Leitner spaced-repetition engine brings back exactly what you're about to forget.
- Real content. 5,000+ words, 990+ kanji, 570+ grammar points across JLPT N5–N1 and two traveler tracks, with furigana, romaji and real example sentences.
