One line: duoBooks is a bilingual reading app for learning languages by reading real books, with one-tap, context-aware translation.
Short: duoBooks lets you read real books in the language you are learning and understand every line. Tap any word or sentence and an instant translation appears right on the page — and it fits the context of the story, so you keep reading instead of stopping to look things up. Save the words you meet to a personal dictionary and review them with spaced-repetition flashcards. duoBooks works on iPhone, iPad, Android phones and tablets, and Android-based e-ink readers.
Long: duoBooks is a bilingual reading app from PlainProg. It is built on one idea: reading real stories is one of the most natural ways to learn a language, and the only thing that usually gets in the way is stopping to look words up. duoBooks removes that friction. Its translation is context-aware — when you tap a word, the app also reads the surrounding sentence, so you get the meaning that fits right there, including idioms and phrasal verbs. The built-in library has more than 3000 books and short stories, mostly in English, with short stories written for beginners. You can also import your own EPUB and FB2 books and read them with the same translation. Words you save become spaced-repetition flashcards, every word and sentence can be read aloud with text-to-speech in 47 languages, and the app interface is available in more than 40 languages. On Android-based e-ink readers such as BOOX and PocketBook, duoBooks switches to a special e-ink reading mode by itself. duoBooks is free to download with the full library included; an optional Full Access subscription with a free trial unlocks unlimited translations and audio.
