About

Otto

Features
Read full description

Otto is a browser that teaches you a language by immersion as you use your phone in the way you've always used it, only now it's at your level all the way from beginner to native. Open any site, search anything, and Otto swaps words on the page into the language you are learning, at your level. Start with a few hundred everyday words and move up to native as you go. Tap a swapped word and it translates itself; save it, and it is yours to practise later. Read the news, recipes, sport, the sites you visit every day. The web becomes your course book, and like your motivation, it never runs out. Set your level in seconds and change it any time. Weave every page, or just the ones you choose. Pause when you want to read as normal. Your usage is shown on every page, with a generous free allowance that renews. Practise what you save: match games, verb drills, quick judgements, built from your own words. Work with a tutor: they see your word bank and set the articles you read. On Apple Watch: follow a book, podcast or film with its swapped words on your wrist, go through the words that need work with a tick or a cross, say a word you heard to save it, and see your next lesson and grammar topic. 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 usage. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
