What is Kaku!?

Kaku! is an Android app for learning to handwrite Japanese. You practice hiragana, katakana and the basic JLPT N5 kanji by tracing them with your finger, with feedback on stroke order.

In Japanese, 書く (kaku) means “to write”: the app is built around learning a character by writing it, not only by recognizing it.

You can start for free: hiragana and katakana are available without paying.

Kanji are unlocked with the Sensei Pass, a one-time purchase of €2.39 (no subscription, yours for good). Starting costs nothing, and unlocking kanji costs about the price of a coffee.
