Furigana on every word
Morphological analysis runs on any text — news, PDFs, what you paste. Furigana appears above every kanji instantly. Toggle always-on, or restrict to unknown words. JLPT color-coding shows N5 vs N1 territory at a glance.
Open any article, paste any text, scan any sign. YoMoo adds furigana above every kanji, opens dictionary lookups in one tap, and saves vocabulary to spaced-repetition review — all in one app, all free.
On iPhone or iPad? YoMoo installs as a Progressive Web App. Open in Safari, tap Share, then "Add to Home Screen" — opens like a native app, no App Store.

Articles read aloud with synchronized sentence highlighting. Listen on the train, or use it as a dictation exercise. On Android, the native TTS voice is noticeably better than browser alternatives.
Every news article comes pre-simplified at N4–N5: simpler vocabulary, shorter sentences, same story. Read the easy version first, switch to the original when ready. Both get full furigana and TTS.
Tap any word for reading, all definitions, part of speech, JLPT level, and verb conjugation notes — without leaving the article. Cached locally, works offline. Save to vocabulary in one more tap.
Saved words enter a review queue at 4h → 8h → 24h → 3d → 1w → 1m intervals. Quiz mode and flashcards. Export directly to AnkiDroid or CSV — reading, definitions, and part of speech included.
Point the camera at a menu, sign, manga panel. ML Kit OCR works on-device, no internet. Plus PDF, DOCX, SRT, and URL import. Everything gets the same furigana engine and dictionary.
Stuck on a passage? One tap reveals the full English translation. Pre-translated articles load instantly. Imported content translates on demand and caches for 30 days.
Paste from anywhere. Upload PDF, DOCX, or PPTX. Drop in an SRT subtitle file from your favorite anime. Full reader treatment on every word.
Recently Read surfaces your last 20 articles for one-tap resume. Reading time, articles finished, words saved, and streaks tracked locally — no account needed.
Instead of scrolling through twelve phones, click a tab.

Every kanji compound gets phonetic furigana above it the moment you open an article. JLPT color-coding shows at a glance whether a word is N5 or N1 territory.
Six content sources cover every level. Every article ships with a curated vocabulary list, English translation, and simplified version — reading support is already there when you open it.
Official-style reading comprehension for all five JLPT levels. Bundled locally — fully offline. Structured exam prep without leaving the app.
Real news in politics, business, science, culture, international affairs — updated regularly. Each comes with the N4–N5 simplified version, full TTS, English translation, and curated vocabulary.
Practical guides on daily life, health, technology, emergency prep. Bilingual content — Japanese with English reference. Good for N3 readers building stamina on practical topics.
Japan's public-domain classics — Sōseki, Akutagawa, Dazai, and hundreds more. Fiction, poetry, essays, folklore. Ready when you outgrow learner readers.
Live access across 9 categories — science, history, culture, technology, geography, politics, economy, sports, society. Unedited native Japanese with full furigana support.
Camera OCR, PDF / DOCX upload, SRT subtitles, or pasted text. Analyze manga, menus, work documents, or anime subs. Same furigana engine, same dictionary.
YoMoo works from N5 through N1, but it shines for learners who can already read kana — typically N4 through N2. If unedited NHK feels impossible on day one, that's not a bug — read the simplified N4–N5 version first.
Other apps do some of this. None do all of it free, in one place, with real-time furigana on anything you import.
