This app allows you to practice hiragana and katakana characters with different methods, by writing the sound or by multiple choice. It supports multiple fonts so you're not seeing the characters written the same way every time, and also you can put your own custom font files. Choose which characters to appear and configure the look of the app to accommodate better for your needs.
Please note that "Kana Writing" requires a keyboard able to input japanese characters!
Further functionality is expected to be added in the future as the creator japanese learning goes further.
