KanjiLock: App Blocker & Focus

Doomscroll less. Read Japanese.

KanjiLock locks your most distracting apps-and the only way back in is to practice kanji. Every scroll you skip becomes a character you can actually read and write. The wall pays for itself.

THE TRADE (and it really does pay for itself)
You pick the apps that eat your day. Apple Screen Time shields them. To unlock, you open KanjiLock and run a short practice session-so the time you'd have lost turns into real Japanese.
• Sprint - 2 min of practice = 15 min unlocked
• Practice - 10 min = 30 min unlocked
• Deep Dive - 20 min = 45 min unlocked

THREE WAYS TO PRACTICE (not just tap-tap flashcards)
• Draw - handwrite the kanji; on-device recognition checks your strokes and animates the correct stroke order.
• Read - match a kanji to its romaji reading.
• Recall - pick the kanji for its English meaning.
Nail all three and a kanji "graduates"-proof it stuck, not just a lucky guess.
