Build your English vocabulary as you read. Point your camera at a textbook or import an image, then tap an English word to see its phonetic transcription, part of speech and Chinese definition, and hear it pronounced. POINT, TAP, LEARN With Live Lookup, recognized words on the page are tappable right in the camera view, no photo needed. You can also capture a full page or import one from your photo library and look up words as often as you like. Show definitions beside the word or in a bottom card, or type a word to look it up manually. HEAR AND TRANSLATE SENTENCES Switch to Sentences mode and tap a whole sentence to hear it read aloud and see a Chinese translation from Apple Translate. READ AND LEARN OFFLINE Text recognition and dictionary lookup run on your device. Core lookup works without an internet connection. Choose British or American pronunciation and speech rate using system voices. KEEP THE WORDS YOU DISCOVER Save words, add your own definitions, and revisit recent scans to continue learning where you left off. On iPad, a split-view layout keeps your words and their meanings side by side. GO FURTHER WITH PRO An optional one-time Pro purchase unlocks batch word extraction, custom vocabulary books, spaced review, dictation (with voice answers), spelling practice, learning statistics, a daily review reminder, and data export and backup. Pro is not an auto-renewing subscription. Purchasing and restoring purchases require an App Store connection. YOUR LEARNING MATERIALS STAY WITH YOU No account required. No ads. WordLens does not upload your scan images, vocabulary books or learning records to a developer-hosted service. You can delete scans, clean up images or erase all user data. If system backup is enabled, your operating system may include app data in its backups. The interface supports English, Simplified Chinese and Traditional Chinese. Dictionary definitions are in Chinese.
