Kakeru: Learn kanji by writing

Kakeru helps you master Japanese kanji writing with a proven, pace-adaptive learning method.
How it works:

Learn - Discover new kanji with step-by-step guided stroke practice.
Immediate quiz - Reinforce what you just learned right after the lesson.
Spaced repetition reviews - The SRS algorithm brings each kanji back at the perfect moment for long-term retention.
Track your progress - See your JLPT-level advancement at a glance from the home screen.

A smart algorithm:
Kakeru uses a hybrid spaced repetition system (SRS) based on the SM-2 algorithm. Kanji you know well come back less often. Kanji you struggle with come back sooner. You always review what you need - never what you already know.
100% offline:
The app works entirely without an internet connection. Learn on the subway, on a plane, or anywhere.
Optional cloud backup:
Create an account to back up your progress and sync it across devices. Sign-up is completely optional - the app works fully without an account.
