**5 Online Dictionaries — Expand Your Lookup Options** LensDict started with two powerful built-in offline dictionaries (WordNet 3.1 and Wiktionary), and now version 1.1 takes your word lookup experience even further. We've added five trusted online dictionaries so you can get richer definitions, example sentences, and usage notes whenever you're connected: • Google Dictionary — Quick, concise definitions powered by Google's language data. • Merriam-Webster — America's most trusted dictionary, with detailed definitions, etymology, and usage examples. • Cambridge Dictionary — Clear explanations with both British and American English pronunciations and example sentences. • Oxford Learner's Dictionary — Designed for English learners, with simplified definitions, grammar notes, and collocations. • Longman Dictionary of Contemporary English — Focuses on the most common 9,000 English words, with frequency indicators and corpus-based examples. You can switch between dictionaries at any time. When you're offline, LensDict continues to work seamlessly with its two built-in dictionaries — no internet required, just like before. **iCloud Backup & Sync — Your Words, On All Your Devices** Your saved words and flash card sets are now backed up to iCloud. This means: • Seamless sync — Access your entire word collection and flash card sets on your iPhone, iPad, or any device signed into the same iCloud account. • Automatic backup — Never worry about losing your saved words. Your data is safely stored in iCloud and can be restored at any time. • Easy device migration — Switching to a new device? Your vocabulary and study progress come with you automatically. Backup and restore can be managed from the Settings screen. You're always in control of when and how your data syncs. **Reorder Flash Card Sets — Organize Your Way** You can now drag and reorder your flash card sets to arrange them exactly the way you want. Put your most active study decks at the top, group sets by topic, or organize them by priority — it's entirely up to you. Simply long-press on a flash card set and drag it to your preferred position. Your custom order is saved automatically and syncs across devices via iCloud. **Why Update?** Version 1.1 makes LensDict more versatile and connected while keeping everything you love about the app — instant camera-based word lookup, offline support, and a privacy-first design. Whether you're a student studying for exams, a traveler navigating foreign texts, or a lifelong learner expanding your vocabulary, these new features are designed to fit naturally into your workflow. Thank you for using LensDict. We're always listening to your feedback — if you have ideas for future improvements, please reach out through the app's Settings page.
