Learn and retain Japanese kanji the proven way β€” 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 β€” the same system behind Anki β€” 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 β€” 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 β€” 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.

Irregular Verbs

Read full description

Master all three forms of English irregular verbs β€” base, past simple and past participle β€” in just a few minutes a day. 175 verbs, hand-picked by real-world frequency and organised into three levels: Core (the 53 verbs you can't live without), Intermediate (65 more) and Advanced (57 for polish and bragging rights). New verbs are introduced in frequency order, so every minute you practise goes into the words you'll actually meet. HOW IT WORKS β€’ Smart reviews. A spaced-repetition schedule shows you each verb right before you'd forget it. Answer correctly and the interval grows; slip up and the verb comes back sooner. β€’ Three difficulties. Recognise the right forms (Easy), type both forms from memory (Normal), or complete a real sentence where you decide which form fits (Hard). β€’ Mistakes aren't punished β€” they're recycled. Any verb you miss returns at the end of the session until you get it right. β€’ Tap the β€œ?” on any card for a plain-English definition and a visual cue. KEEP THE FIRE BURNING β€’ Daily streak with freezes. Miss a day? A streak freeze saves your run β€” you earn one every week of practice. β€’ Combos reward accuracy within a session. β€’ Boss rounds. Every chapter of 10 verbs ends with a hard-mode, no-mistakes challenge. Beat the boss to seal the chapter in gold and earn a bonus freeze. β€’ Blitz. A 60-second speed round: how many forms can you nail? Beat your record and discover new verbs along the way. β€’ Collection. Watch all 175 verb cards light up as you learn β€” from grey silhouettes to mastered gold. β€’ History. Every session, boss fight and Blitz run is logged, so you can see your work add up. NO STRINGS ATTACHED No account. No ads. No subscriptions. No tracking. Your progress lives on your device and nowhere else. WHO IT'S FOR Learners from A2 to C1, IELTS and Cambridge exam candidates, teachers and tutors after a quick warm-up tool, parents helping with homework β€” and anyone tired of second-guessing whether it's β€œswam” or β€œswum”. Download it, do one session a day, and irregular verbs will stop being the annoying part of English.
