Full description

Dunno is a free English dictionary and translator that works completely offline. Look up any English word, translate text or photos, hear native pronunciation, and build your own vocabulary notebook — no internet required. ★ OFFLINE ENGLISH DICTIONARY Look up English words, grammar, prepositions and sentence patterns without a connection. Every entry in the dictionary includes definitions, examples, word forms, irregular verbs, synonyms, antonyms and related words, with illustrations. Autocomplete predicts the word from the first few letters. ★ TRANSLATE BY PHOTO, VOICE OR TEXT Point your camera at a word to translate it instantly, speak to search hands-free, or paste a long passage. Dunno translates English into 89 languages and back: Spanish, French, Chinese, Japanese, Korean, Vietnamese and more. ★ IDIOMS AND COLLOCATIONS Find the natural English phrase instead of a word-for-word translation — the part most dictionaries leave out. ★ BRITISH AND AMERICAN PRONUNCIATION Every word comes with audio in both accents. Record yourself, compare with a native speaker, and get a score that shows exactly which syllable to fix. ★ ENGLISH GRAMMAR CHECKER Paste any sentence to catch spelling and grammar mistakes, with a clear explanation of each correction. Writing English becomes faster and more accurate. ★ ENGLISH GRAMMAR BY LEVEL 172 grammar structures with examples, ordered from easy to advanced, so you always know what to learn next. ★ TOEIC PRACTICE TESTS Full mock tests built to match the real exam, with answer keys and a detailed explanation for every question. Tests are sorted by difficulty. ★ VOCABULARY NOTEBOOK Save any word with one tap and review it with flashcards and quizzes to remember twice as much. Built-in word lists cover 3,000 TOEIC words plus IELTS, TOEFL and SAT vocabulary, organised by subject, level and school grade. Track how many words, sentences and grammar points you have learned. ★ LEARN IN SPARE MOMENTS A new English word every day, plus vocabulary practice right on your lock screen. ★ ASK THE COMMUNITY Over 100,000 learners share questions and answers about English every day.
