Graded readers for language learners Eppika offers graded readers based on familiar books, classics, stories, and practical nonfiction. Every text is adapted for levels A1–B2, with vocabulary and grammar matched to the right difficulty. Beginners can start reading without feeling lost, while more experienced learners can progress to richer, more complex texts. Each book is challenging enough to help you improve but clear enough to enjoy. Audiobooks for language learning Use Eppika to read and listen in Spanish, English, French, German, or another available language. Native audio helps improve listening comprehension and pronunciation while developing a better sense of the language’s natural rhythm. Switch to Audiobook Mode when you want to learn during a walk, commute, workout, or before bed. Instant word translation Tap any unfamiliar word for an instant translation without leaving the story. Understand new vocabulary exactly when you need it and keep reading without switching to an external dictionary or translating every sentence.
