About

Kanji Flash Study

Features
Read full description

Learn and retain Japanese kanji the proven way — with spaced repetition. Kanji Flash Study covers all 1,318 kanji from JLPT N5 through N1, complete with meanings, on'yomi and kun'yomi readings, stroke counts, and example vocabulary. The built-in SM-2 algorithm — the same system behind Anki — schedules your reviews at scientifically optimal intervals so you spend more time on what you're about to forget and less time on what you already know. HOW IT WORKS Pick your JLPT levels and session size, then tap Start Review. Each card shows a kanji character — tap to reveal its meaning, readings, and an example word. Rate your recall as Again, Hard, Good, or Easy, and the app adjusts the next review date automatically. Cards you miss are re-queued in the same session so you always end on a strong note. FEATURES - 1,318 kanji across JLPT N5, N4, N3, N2, and N1 - SM-2 spaced repetition for efficient long-term memorization - On'yomi and kun'yomi readings with example words and translations - Searchable kanji library with level filters and progress indicators - Statistics dashboard with streak tracking, accuracy, activity heatmap, and per-level breakdown - Daily study reminders via notifications - Fully offline — no account, no internet, no subscriptions - VoiceOver and Reduce Motion accessibility support - Clean, native SwiftUI interface designed for focused study BUILT FOR EVERY LEARNER Whether you're starting with basic N5 kanji or tackling advanced N1 characters, the app adapts to your pace. Select one level or all five — your progress is tracked independently for each. YOUR PROGRESS, YOUR DEVICE All study data stays on your device. No sign-up required, no data leaves your phone.
