KanjiGrader

KanjiGrader analyzes kanji usage by school grade and colors each kanji according to the grade in which it is learned. Enter a sentence, press the judgment button, and you’ll see a color-coded map of kanji with grade-based coloring and per-grade counts.

Designed for Japanese educators, parents, and language learners, it helps users focus on essential kanji first. Features include adjustable grade ranges, multiple color schemes, the ability to emphasize a target grade, text-size control, and clipboard sharing. Some features unlock with in-app purchases for a smoother study workflow.
