YomiStudy is a Japanese reading companion built for language learners. Browse any Japanese website. Tap any kanji to instantly see: • Furigana (the hiragana reading) • Definition from the system Japanese dictionary • On-device translation into your language • High-quality text-to-speech (Kyoko voice) NEW: Photo OCR Recognize Japanese text from your camera or photo library and read it with furigana: • Photo mode — furigana laid directly over the kanji in your image • Reader mode — recognized text rendered as a clean Reader page with the same tap-to-translate / dictionary / save-word actions • Save a scan and reopen it later in either Photo or Reader mode Note: vertical (tategaki) text isn't supported — Apple Vision's vertical OCR isn't reliable enough. Reader Mode strips ads and clutter from articles and annotates every kanji with furigana inline above the characters — perfect for long-form reading practice. Bookmark words you want to remember. The built-in flashcard quiz with spaced-repetition scheduling helps them stick. Save articles for offline reading so you can study on the train or on a flight. Customize your experience: • Font size (S/M/L/XL) • Theme: light, dark, or sepia • Furigana display: always on or off • Translation target language follows your iOS setting Built entirely on Apple's on-device frameworks. No accounts, no API calls, no ads, no tracking. All your saved words, pages, and review history stay on your device. YomiStudy is for anyone studying Japanese — JLPT N5 to N1, casual learners, or fluent readers who just want furigana now and then for unfamiliar terms.
