You don't need 20,000 words. 1,000 is enough. The most common words of a language cover most of everyday conversation. 1000 Words teaches you exactly those – with a smart vocabulary trainer, audiobooks and videos that fit into your day. SMART TRAINER WITH SPACED REPETITION The trainer brings each word back right before you would forget it (SM-2). Practise with flashcards, typing, listening and speaking – your pronunciation is checked. Mix mode, a matching game and a timed blitz round keep it varied. One tap shows every word that is due today. AUDIOBOOKS – FOR THE COMMUTE OR FOR FALLING ASLEEP Calm vocabulary audiobooks with triple repetition: first the word in your language, then in the language you are learning. Listen in the car, on a walk or in bed. Reviewing before sleep is a good habit – sleep helps your memory keep what you practised during the day. VIDEOS WITH PICTURES AND EXAMPLE SENTENCES See, hear and repeat the 1000 most important nouns, verbs, adjectives and phrases – each with a picture, an example sentence and clear audio. MY WORDS – YOUR OWN DECKS Type any word: AI translates it and adds an example sentence. Build a deck for every language pair, share it with friends or discover decks from other learners. Import your own word lists (CSV, TXT, Excel or PDF) and turn them into personal videos and audiobooks. AI STORIES AT YOUR LEVEL Short stories written for your level (A1–C1), with audio. E-BOOKS, PDF WORD LISTS & QUIZZES Read along with e-books, print vocabulary lists and test yourself with quizzes. PROGRESS, STREAK & LEAGUE See what you have learned, keep your daily streak and climb the league. RELAX MODE Listen with calm background sounds such as rain, a fireplace or a quiet shoreline. 33 LANGUAGES, ANY COMBINATION English, Spanish, French, German, Italian, Portuguese, Dutch, Swedish, Danish, Norwegian, Finnish, Polish, Czech, Slovak, Croatian, Hungarian, Romanian, Bulgarian, Greek, Russian, Ukrainian, Turkish, Arabic, Persian, Hindi, Thai, Vietnamese, Indonesian, Swahili, Afrikaans, Chinese, Japanese and Korean – over 1,000 language pairs. The trainer, quizzes, e-books and word lists are available for every pair, and new videos and audiobooks are added every week.
