$2.99
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.

Ratings & Reviews
What's New in 1.3
• Conjugation panel on iPhone: see every verb and adjective form (dictionary, polite, te-form, ta-form, negatives, and N4+ potential) right in the card detail view.
• Card-type breakdown bars on iPhone Stats now use the same 4-tier style (mastered / studying / struggling / unstudied) as the JLPT level bars.
• Watch study history is now restored after reinstalling the Watch app — your 30-day window and recent-stats weighting come back from your iPhone automatically.
• Expanded part-of-speech labels (na-adjective, adverb, expression, and more) on the Watch back face.
• Stability: fixes for a rare second-launch freeze and a safe-mode recovery path if the Watch app ever hits a crash loop.
