Read full descriptionHide full description
Read the books you love - and, whenever you like, read them in two languages, side by side. Parallèle Reader is a calm, aesthetic everyday reader for your books. It also has a language companion built in: open a book in its original language and a clean translation appears right beside it - there when you need it, out of the way when you don't. FEATURES - Read your own EPUB, PDF, and text files (five timeless classics included free, in their original languages) - Side-by-side bilingual reading in split screen — original and translation, page by page - Translate offline with Apple's on-device engine — no internet needed once your languages are downloaded, or connect your own DeepL key - Hide the translation and reveal it with a tap to test yourself - Long-press any word or passage to look it up, highlight it, add a note, or save it - A personal vocabulary that builds as you read — export it as a TSV file - Highlight in five colors, add notes, and bookmark pages — all organized by book - Reading stats with a heatmap that turns your daily progress into a streak — minutes read, books finished, and more - iCloud sync keeps your reading position, highlights, and vocabulary together across iPhone and iPad - Collections and smart shelves for Favorites and Finished, plus search by title, author, or language - Four reading themes (Warm Paper, Sepia, Light, Dark) - Classic serif fonts, adjustable size, spacing, and margins, and a focus mode WHO IT'S FOR You just love reading — a distraction-free reader for your own library, with stats that make the habit stick. Language learners — read authentic books instead of exercises; reading in context teaches what flashcards can't. Heritage and bilingual readers — move freely between both your languages on every page. Anyone after a book that was never translated for sale — read the original with a translation alongside. HOW IT WORKS Open one of the included classics, or import your own EPUB, PDF, or text file. In split screen, the original and a clean translation appear side by side, page by page — on your device with Apple Translate, or through your own DeepL key. Long-press a word or passage to look it up, highlight it, add a note, or save it to your vocabulary. Prefer to test yourself? Hide the translation and reveal it with a tap. PRICING Try Parallèle Reader free for 7 days. After the trial, a single one-time purchase unlocks the full app. PRIVACY Your reading stays private. iCloud sync is optional and connects only your own devices through your Apple ID — your reading habits never reach our servers. Translate entirely on-device with Apple Translate, and if you add a DeepL key, it's stored securely on your device. Whether you're rereading an old favorite or finally reading that novel in its original language, Parallèle Reader makes reading feel good — and quietly makes you better at it.
