Hi - Learn Languages

Most language apps assume you already speak English. Hi doesn't. Whether you think in Vietnamese, Hindi, Thai or Turkish, you learn your new language through the one you already know — every explanation, every hint, every correction. Nothing gets lost in a language you're still figuring out. Right now you can learn English and Japanese, with more languages arriving soon. LEARN IN YOUR OWN LANGUAGE The entire app speaks your language, not just English. Choose from 20 interface languages: English, Spanish, French, German, Italian, Dutch, Romanian, Russian, Ukrainian, Turkish, Hindi, Bengali, Burmese, Thai, Indonesian, Vietnamese, Japanese, Korean, Chinese (Simplified and Traditional).
