Short description
DuoPage is a reader made for the two screens of iPhone Duo: fold it and your book’s cover is on the outside; open it and read two pages side by side. PDF, ePub, Word and notes. Pay once.
Long description
DuoPage turns every document into a real book, with a cover, a spine and a ribbon. Close an iPhone Duo and the book you’re reading appears on the outer display with how far you’ve come; open it and two paper pages lie side by side, the spine right on the hinge, with text kept clear of the fold. On any other iPhone or iPad, the cover greets you when you return to the app.
Readers can import PDF, ePub, Word, text, Markdown and web pages, organise them on shelves, and design covers in Cover Studio from 14 templates. Highlighter, pens, typed notes and stickers work with a finger or Apple Pencil, and notebooks come in lined, grid, dot and Vietnamese school paper. Study tools — summaries, questions with page citations, flashcards — run on device with Apple Intelligence, or with a free offline model on iPhones without it. Nothing is uploaded, and there are no accounts or ads. DuoPage Pro is a one-time purchase with Family Sharing.
