ippun is a 60-second kanji workout for foreign learners of Japanese. If you already know your kanji individually but still stall when reading real Japanese — that gap between "I recognize 学" and "I can read 学校, 学生, 学習, 学者" — that's the gap ippun is built to close. Each run is one minute. Eight rounds. In every round, you're given an anchor kanji at the center and a tray of drifting characters. Find the real compounds. Match them before the timer runs out. Repeat tomorrow. It's small on purpose. The minute isn't a constraint to game around — it is the workout. ---------- WHAT'S INSIDE — Thousands of compounds, sourced from JMdict and reviewed against JLPT vocabulary tiers — Four difficulty presets: Easy (N5–N4 beginner words), Normal (N3–N2 everyday vocabulary), Hard (N2–N1 compounds that catch even native readers), and Mixed (an even draw across all three) — Focus mode: pick which kanji you want to drill, and the game builds the session around them — Collection and Kanji Dex: every compound you encounter is saved, with readings, meanings, components, and related compounds — Learning states (new / learning / mastered) so the app shows you what you've actually internalized — Full English and 日本語 interface, with furigana on every compound ---------- WHO IT'S FOR ippun is built for learners around JLPT N4–N3 who already recognize individual kanji and are now working on reading compound vocabulary fluently. If you have a main study routine — a spaced-repetition app, a textbook, a class — ippun is the supplement that targets a specific gap: turning kanji you "know" into compound words you can read at speed. If you haven't started learning kanji yet, ippun isn't the right place to start. Build a kanji foundation first, then come back. ---------- WHAT'S NOT IN IT — No ads — No account or sign-up required to play — No notifications nagging you to come back — No personal data collected; anonymous, opt-out analytics only ---------- PRIVACY ippun does not collect your name, email, location, IP address, or advertising ID. Progress is saved on your device. Anonymous, opt-out-able usage data helps us fix bugs and improve the app — and nothing else. Full policy in the app and at our privacy page (linked below). ---------- Made carefully, for one purpose. We read every email — if a compound looks wrong, or a reading is off, or you want to suggest something, write to us.
