Collecting words is easy. Meeting them again at the right moment is not. SnapDic makes saving a word take one tap, then lets FSRS decide when you should see it again. Three ways to collect a word • Point your camera — on-device OCR reads text from books, signs, and screens; tap a word to see its meaning • Share from any app — select a word while reading and send it straight to your vocabulary • Search directly — look it up in the dictionary you prefer and save it on the spot Memorize with FSRS FSRS (Free Spaced Repetition Scheduler) tracks the stability and difficulty of each word separately and picks your next review date from them. Words you already know drift further apart; words you keep missing come back sooner. You never have to decide what to review or when. Features • Camera OCR dictionary — English, Korean, Japanese, and Chinese • Offline dictionaries — look words up with no connection • Share sheet intake — save a word without leaving what you were reading • Multiple vocabulary lists • FSRS-based review mode with automatic scheduling • Pick the dictionary you want at save time • Search history • Adjustable split — size the camera and dictionary panes to taste Made for • Readers who keep skipping over words they don't know • Anyone who builds vocabulary lists and never opens them again • People who want to remember words for years, not until the test This app is subject to Apple's standard terms and conditions (EULA).

Everything runs locally on your device. **How it works** Simply aim your camera at a book, article, menu, or sign. LensDict automatically detects the word at the center crosshair, highlights it, and shows the definition in a floating card. Tap the screen to pause and explore deeper. **Powerful lookup** • Two built-in dictionaries: WordNet 3.1 and Wiktionary — with automatic fallback if a word isn't found in one • Long-press any word in a definition to look it up (deep lookup) • Lemmatization recognizes word forms — "running" finds "run", "children" finds "child" • Text-to-speech pronunciation for every word • Works entirely offline — no internet connection required **Save & organize** • Bookmark words with one tap — each save captures a snapshot of what you were reading • Add personal notes with color coding to any saved word • Browse saved words with swipe navigation **Flash Card Sets (Premium)** • Organize saved words into custom-colored flash card decks by topic, lesson, or difficulty • Two-sides study mode: see the word first, tap to reveal the definition — perfect for self-testing • Shuffle mode for randomized review • Copy or move words between sets • Unlimited saved words (free users can save up to 50) **Premium Plans** • Monthly, yearly (with 7-day free trial), or one-time lifetime purchase • Free users enjoy full camera dictionary and up to 50 saved words **Privacy first** • No account required • No data leaves your device • No tracking, no ads Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
