Otto teaches you a language by immersion, in everything you already do on your phone, at your level from beginner to native. Words in what you read, watch and listen to are swapped into the language you are learning, a few at first and more as you grow. Tap a swapped word and it translates itself; save it and it is yours to practise later. FOR YOU A feed made for you: short videos with woven subtitles, articles, posts, podcasts and books, all at your level. Swipe a card right to like it, left if it is not for you, and the feed learns what you enjoy. Stories from the topics and creators you like sit at the top. WATCH, LISTEN, READ Films and series with woven subtitles. Podcasts woven as they play. Articles and books at your level, with a word bank that grows as you go. THE WEB, AT YOUR LEVEL Open any site or search anything, and the page is woven for you. Pause it whenever you want to read as normal. Ads and trackers are blocked as you browse. YOUR LEVEL, IN SECONDS Choose your level on a real page and see exactly how much changes. Change it any time. PRACTISE WHAT YOU SAVE Match games, verb drills, quick judgements and a daily homework plan, built from your own words. Work with a tutor if you have one: they can see your word bank and set what you read. ON APPLE WATCH Follow a book, podcast or film with its swapped words on your wrist, review the words that need work, and save a word you heard by saying it. ELEVEN LANGUAGES Learn Spanish, French, German, Italian, Portuguese, Chinese, Japanese, Korean, Hindi or Arabic from English, English from any of them, and French, Spanish, Italian or Portuguese from one another. Free to use, with Pro and Max plans for more. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
