## What is EPUB Reader?

Duotext is a book reader with subtitles: the original line on top, its translation right underneath — with the same on/off toggle you know from video players.

16 CLASSIC READS IN YOUR LIBRARY
• Three complete starter texts, free to read.
• The English language setting starts with three French fables by Jean de La Fontaine, with ready-to-read English translations.
• Other language settings start with English stories by Kate Chopin, O. Henry and Oscar Wilde.
• Thirteen more texts with Pro: French stories by Maupassant and fables by La Fontaine for the English language setting; English stories, including four by Saki, for other settings.

TRANSLATION THE WAY YOU WANT IT
• Tap to translate — free, in every book: touch the mark after a sentence and its translation appears
• Always-on translation under the text, with no tapping at all — with Pro
• Choose how the text is split: by line, by sentence, or by paragraph — with Pro
• Tap a single word to see what it means in that exact sentence

BUILD VOCABULARY FROM REAL BOOKS
• Press and hold a sentence to save a word together with the context you met it in
• Free: up to 20 saved words. Pro: an unlimited dictionary

BRING YOUR OWN BOOKS — WITH PRO
• Import EPUB and TXT files
• Paste any text
• Save an article from the web by link

A READER FIRST
• Six reading themes, serif, sans serif and rounded fonts, adjustable type size — all free
• Covers, reading progress, and your place in the book
• Your books stay on your device

HOW TRANSLATION WORKS
Duotext uses the translation built into iOS, so text is translated on your iPhone. The first time you use a language pair, iOS downloads that language model, which needs an internet connection; after that, translation runs on your device. You can translate into the languages your device supports for translation. No account, no sign-up.

WHAT IS FREE AND WHAT IS PRO
Free: 3 complete stories, tap to translate in any book, up to 20 saved words, and every theme, font and type size.
Duotext Pro adds: 13 more stories, always-on translation under every line, the by line / by sentence / by paragraph layouts, importing your own EPUB and TXT files, pasted text and links, and an unlimited dictionary.
