Write Japanese teaches you to draw the Japanese kanji, hiragana, and katakana. It covers the basic kana alphabets, and the first ~2,000 kanji characters. Write Japanese teaches you characters you don't know, reviews your drawing of characters you do know, and dynamically repeats characters you are still learning.
Write Japanese uses a Spaced Repetition system (SRS) to repeat characters you've correctly drawn at timed intervals, to maximize your memorization.
Pre-made character lists are included for all 5 levels of the Japanese Language Proficiency Test (JLPT), and for all levels of the Joyou Kanji, learned by Japanese schoolchildren. You can also create your own custom lists.
This is an Android exclusive software. It contains no advertisements. Hiragana, the Joyou kanji level 1, and the JLPT level N5 are free, while the remaining katakana and kanji require a single, one-time in-app purchase to unlock.
