Twinread: Bilingual Book Reader

Twinread, the bilingual EPUB reader for iPhone and iPad

Twinread is a bilingual book reader that turns any EPUB, PDF or text into a parallel text: the original on one side, your language on the other. Import your own book, read it in two languages, tap a sentence to see its twin light up in the translation, and save the words you meet. Translation runs on your iPhone with Apple's on-device Translation, so your books stay private and keep working offline.

Why readers choose Twinread

• Real books, not AI stories. Read your own EPUB, PDF or pasted text, articles shared from Safari, or free public domain classics from Project Gutenberg.

• Side-by-side bilingual reading. Facing pages, stacked, sentence by sentence, or hidden until you tap. Every sentence is aligned with its translation.

• A vocabulary trainer built from your books. Tap a word for its definition and pronunciation, save it with its sentence, and review it with spaced repetition.

Read books in two languages, sentence by sentence

Parallel text is one of the oldest ways to learn a language: you read a real story in the language you are learning and check the meaning without leaving the page. Twinread does this for any book you own. Choose the book's language and yours, and Twinread translates it chapter by chapter, keeping each sentence next to its twin. Read on iPhone, on iPad with two columns, or on the foldable iPhone Duo, where the original and the translation become two real facing pages.

An EPUB reader with translation and a dictionary

Twinread opens EPUB files without DRM and PDFs with selectable text from the Files app, and reads web articles you share from Safari. Tap any word to open the dictionary built into iOS, hear it spoken aloud, and save it to your vocabulary. Twinread works with 20 languages, including Spanish, French, German, Italian, Japanese, Chinese, Korean and Portuguese. Once a language pack is downloaded, translation works without an internet connection.

A vocabulary trainer and reading comprehension habit

Words are easier to remember when you meet them in a real sentence. Every saved word keeps its sentence and becomes a flashcard with spaced repetition. A daily reading goal, gentle reminders and reading stats help you read a little every day.

Questions readers ask

What is a bilingual book?

A bilingual book shows the same text in two languages, usually on facing pages. Twinread creates a bilingual version of the books you already have instead of limiting you to a fixed catalog.

Which app can read books in two languages on iPhone?

Twinread reads EPUB, PDF and text in two languages on iPhone and iPad, with the original and the translation side by side or sentence by sentence.

Is reading parallel text good for learning a language?

It is a good fit for intermediate learners: you follow a real story, check the meaning only when you need it, and build vocabulary in context.

Does Twinread work offline, and is it free?

Yes, once the language pack is downloaded. Twinread is free to download: the first 3 chapters of every book in two languages, 50 saved words and 1 article a day are free. Twinread Pro unlocks every chapter, unlimited words, spaced repetition, read aloud and iCloud sync, with a Weekly plan (3-day free trial) or a Yearly plan. Prices are shown in the app and on the App Store. Translation needs iOS 18 or later.
