About this app
Omedetou is a complete Japanese course that lives on your phone. Start at the very beginning — the hiragana and katakana charts, one sound at a time, with audio and pronunciation notes for every character. Then work upward through more than fifty grammar chapters, from your first sentence to N1 (master level) material, each with worked examples, vocabulary and practice questions. CLASSROOM The Classroom walks you through the whole course as one linear path with no subscription required. Each class teaches a chapter a single idea at a time: a grammar points explained, worked examples, a short quiz to make sure it stuck, then the chapter's vocabulary and kanji as flashcards — and finally the test. Finish a chapter and the next one is waiting. Every learner can walk the path from あ to N1. WHAT'S INSIDE • Attend Class — a guided lesson path through the entire course: teaching, examples, quizzes, flashcards, tests • Kana from zero — 28 lessons across hiragana and katakana, with readings, audio and example words • Fifty-plus grammar chapters — N5 through N1, plus counters, dates, keigo and everyday slang • Graded tests — sit them on a schedule, get a report card and a running GPA • Flashcards — vocabulary and kanji, scheduled by a spaced-repetition system that shows you a card just before you'd forget it • Audio study — hands-free vocabulary and sentence practice that keeps playing with the screen off, over headphones or your car stereo • A real dictionary — thousands of entries, searchable in English or Japanese, with conjugation tables and audio • 1,100+ kanji — readings, meanings and example words • Reading passages — graded comprehension practice with full furigana • Particles, cheat sheets and conjugation drills • Custom lessons — build your own sets from anything in the app BUILT FOR READING JAPANESE Furigana sits above every kanji, and one slider controls how large Japanese text appears throughout the app — so readings stay legible whatever your eyesight. Anything can be read aloud, and you can search the dictionary by speaking instead of typing. YOUR PROGRESS, YOUR DEVICE Everything you do is stored on your iPhone. There are no accounts, no sign-up, no advertising, no analytics and no third-party trackers. Turn on iCloud sync and your progress follows you to another device through your own private iCloud — which nobody else can read. You can export a backup at any time. The app works completely offline. It never needs a connection to teach you anything. A home screen widget shows a word from your studies and rotates it through the day. There are also a few things hidden in the app for the curious.
