Suisui Kana

Made by a developer who, before every trip to Japan, swore they'd finally memorize hiragana and katakana — and failed every time.

Suisui Kana is the smoothest way to learn the Japanese kana — by actually writing them.

すいすい ("smoothly"): see or hear a reading, draw the character on screen, and an on-device model instantly checks your strokes. No multiple choice, no typing — real handwriting, the way kana is meant to be learned.

✏️ Write to learn
• A reading appears; you write the kana by hand.
• On-device recognition (Google ML Kit) checks it — works offline.
• A per-character write timer keeps you sharp (or turn it off).

📈 Smart, adaptive practice
• Every character has a mastery level (1–5).
• Weak characters show up more often; mastered ones less (but never disappear).
• The Study tab shows your progress in aiueo order, for both hiragana and katakana — tap any card for details.

🔤 Both syllabaries
• Practice hiragana only, katakana only, or both at random.

🗣️ Hear it in Japanese
• Every reading is spoken with Japanese text-to-speech.

🖼️ Word mode
• Optional: a simple example word + picture for each kana, read aloud as "word の kana".

🌗 Make it yours
• Light or dark theme.
• Interface in English, 中文, or 한국어.

🔒 Private by design
• No account, no ads, no tracking. Your progress stays on your device.

Start writing — suisui!
