Two kanji, one reading, a few seconds to choose. Drill the characters you actually confuse, not random ones.
Two kanji. One reading. A few seconds to choose.
FastKanjiQuiz drills the thing that actually makes kanji hard: telling apart the characters that look almost the same. Every card sets a kanji beside the one you are most likely to mistake it for, shows a reading, and starts a clock. You choose. The right one is circled, the meaning of the other one appears, and the next card comes.
WHAT IS IN IT
All 2,230 kanji, from JLPT N5 to N1, in small themed groups you can finish in one sitting.
Every kanji is paired with the characters people genuinely mix it up with, not with random ones. Learning to tell them apart is the whole point.
Spaced repetition schedules each character for roughly the day you were about to forget it. Speed is treated as information: recall you had to work for is scheduled differently from recall that was instant.
BUILT FOR DAILY USE
A session runs until you leave it. There is no arbitrary end.
Regular rests, each with a piece of Japanese history worth reading.
Statistics that tell you something: your streak, your accuracy, and the exact pairs you keep falling for.
A browser for all 2,230 kanji, searchable by character, reading or meaning.
Sounds designed to be heard a thousand times without wearing thin, and an app that works perfectly with them switched off.
