Read real English books

duoBooks comes with more than 3000 English books and short stories. You get classic novels, short fiction, and stories made for beginners. The beginner stories use simple words and short, clear sentences. You read real English written for readers, not textbook exercises. That is what helps the language stay with you.

Understand every word

When a word or sentence confuses you, tap it. duoBooks looks at the text around it and shows the meaning that fits this sentence. This works for idioms and phrasal verbs too, so you never have to guess. The translation appears right on the page. You stay with the story instead of stopping to look something up.

Remember the words you learn

Save the words you want to remember to your own dictionary. Each word is saved with the sentence where you found it. duoBooks turns these words into flashcards. It shows them to you again right before you would forget them. You can also hear any word or sentence read aloud to practice your pronunciation.

From beginner to advanced

Whatever your English level, there is a book for you. Are you new to reading? Start with short stories made for beginners. They use simple words, repeated often, in short sentences. Are you already advanced? Read real novels and classic literature. An instant translation is ready for any rare word, idiom, or small difference in meaning. These small details help you perfect your English. And since every word is one tap from a translation, you can start a little above your level and improve over time.
