WRITE ON YOUR WRIST • Trace every kana directly on the Apple Watch screen • A faint guide shows the correct stroke order, animated stroke by stroke • Instant scoring tells you how close your shape and order were • Gentle haptics tap your wrist as each stroke registers • Turn the Digital Crown to move between characters • Flip any card to see its romaji and an example word LEARN, DON'T JUST DRILL • Smart daily review (spaced repetition) brings back the kana you're about to forget • Add a set number of new kana each day at your own pace • Optional daily reminder keeps the habit going • Track your progress over time PRACTICE ON IPHONE TOO • The same tracing experience on a larger canvas for focused sessions • Build custom practice sets and send them straight to your Watch WHAT YOU CAN PRACTICE • Free: the full hiragana syllabary • WristInk Pro (one-time purchase): unlock katakana plus voiced and semi-voiced kana (dakuten & handakuten) Whether you're starting Japanese from zero or finally nailing katakana, WristInk makes daily handwriting practice something you'll actually keep up.
