WHAT YOU GET

• 6,300+ cards across all JLPT levels (N5 through N1) plus colloquial vocabulary from everyday media • 4 deck: Kanji (with radicals, on'yomi, kun'yomi), Vocabulary, Kana (hiragana & katakana), and Counters • Kanji cross-referencing — vocabulary cards show the kanji they contain, with meanings and readings • Card meanings in English, Portuguese (PT-BR), and Spanish — set your language on iOS and your Watch follows

HOW IT WORKS

Tap a card to flip it — or switch to swipe gestures (right = hit, left = miss) for a less crowded back face. Mark your answer and move on. Cards you miss come back more often through smart weighted shuffling — so you spend time on what you actually need to learn.

Pick your level, pick a deck, and start reviewing. That's it.
