LensDict is a zero-input camera dictionary. Point your camera at any text and instantly see word definitions — no typing, no tapping, no internet connection needed. 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/
