Koalalingo teaches a language the way people actually pick one up: through short stories you can finish in ten minutes, with every exercise built from the sentences you just read. 55 LANGUAGES, ONE SUBSCRIPTION Choose from Afrikaans, Albanian, Arabic, Breton, Catalan, Chinese, Croatian, Czech, Danish, Dutch, English, Esperanto, Finnish, French, Galician, German, Greek, Haitian Creole, Hausa, Hawaiian, Hebrew, Hindi, Hungarian, Icelandic, Igbo, Indonesian, Irish, Italian, Japanese, Javanese, Korean, Kurdish, Lingala, Luxembourgish, Malay, Maori, Norwegian, Persian, Polish, Portuguese, Romanian, Russian, Scottish Gaelic, Slovak, Slovenian, Somali, Spanish, Swahili, Swedish, Tagalog, Turkish, Vietnamese, Welsh, Wolof and Yoruba. Switch whenever you like, and your progress in each is kept separately. NEW ALPHABETS MADE EASY Greek, Russian, Arabic, Hebrew, Persian and Japanese start with short alphabet lessons: each letter with its sound, a tip to remember it, and a word from the course. In these languages, and in Chinese, Korean and Hindi, every sentence, every word and every exercise tile of A1 shows its pronunciation in Latin letters (pinyin for Chinese), and you can switch it off in your profile once the script feels familiar. In the first chapters, each story opens with its words before its sentences. Arabic, Hebrew and Persian read from right to left. HOW A LESSON WORKS Read a story, one sentence at a time, with the translation a tap away. Then rebuild those same sentences yourself: drag the words into order, fill the gap, or listen and reconstruct what you heard. Match words to their translations, choose what a word means, and close each story with a short quiz. Nothing is drilled that you have not just met in context. THIRTY CHAPTERS PER LEVEL Every course runs to thirty chapters and up to a hundred and fifty stories at A1 beginner level. Thirty-two languages continue into A2, and thirteen go on through B1 and B2: English, French, Spanish, German, Italian, Portuguese, Turkish, Arabic, Russian, Japanese, Chinese, Korean and Hindi. In forty-five languages, every sentence and every word is read aloud by a recorded voice rather than by your phone. WORDS THAT COME BACK New words enter a review schedule and return exactly when you are about to forget them. A swipe game turns that review into something you can do in a queue. NO ACCOUNT, NO ADVERTISING The app opens straight into a lesson. There is no sign-up form, no advertising, and nothing about you is sold to anyone. SUBSCRIPTION Koalalingo Premium unlocks every chapter in every language. 4.99 EUR per week or 39.99 EUR per year, after a seven-day free trial. Cancel any time in your Account Settings. Payment is charged to your Apple ID at confirmation of purchase, and renews automatically unless auto-renew is turned off at least 24 hours before the period ends.
