Kasane: Kanji Study

Kasane helps you learn and keep essential kanji. Meet a few new kanji at a time with their stroke order, readings and words, then review a short session each day while the app schedules every card for the moment you are about to forget it.

The kanji come in lessons of 16, from the simplest shapes to everyday compounds, each with the words that use them.

REVIEW • Kanji and words are reviewed separately, each in short sessions you size yourself • Kanji → meaning, meaning → kanji and word → meaning cards • Multiple choice, or recall the answer and rate yourself • FSRS scheduling with the next interval shown on each rating button

LEARN • Learn sessions: meet the next few kanji with their words, then get quizzed on them before they enter your reviews • Readings, meanings, JLPT level and example words for every kanji • Animated stroke order, and the components a kanji shares with others • Example sentences for words, with pronunciation and optional furigana • Your own memory notes on any kanji

PRACTICE • Trace over the strokes, or write from memory and compare • Type the readings of a lesson's kanji and words • Custom study: cram any lessons or a JLPT level without touching your schedule • Leech list with look-alike kanji side by side

TRACK • Progress per lesson, streak, reviews per day and a due forecast • True retention, a year heatmap and accuracy per card type • Daily reminder and home-screen widgets • Export your review history as a CSV file
