## WatchNihongo Description
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.

BUILT FOR YOUR WRIST

• Fully standalone — works without your iPhone
• Completely offline — all content is bundled, no downloads or logins
• Designed for 1–2 minute micro-review sessions
• Haptic feedback on every interaction

iOS COMPANION

• Browse all 6,300+ cards by type with per-card accuracy, mastery badges, and romaji search
• Track progress with tier bars (mastered / studying / struggling / unstudied), accuracy trends, and level drill-downs
• Tap through kanji cross-references to explore how words connect
• Configure language, input mode, and mastery thresholds — all sync to your Watch
• Toggle romaji on or off above kanji while browsing — useful whether you're drilling readings or just exploring
• Study data syncs automatically between Watch and iPhone
• iCloud backup for your study history

PRIVACY FIRST

No accounts. No analytics. No tracking. Your study data stays on your devices.
