Pageo is a Calibre companion app for iPhone and iPad: a Calibre ebook reader that syncs your library over Wi-Fi in both directions, converts any ebook to EPUB and reads your books aloud in 31 languages. It connects directly to the Content Server built into Calibre — no cables, no account, no hassle. ▶ TWO-WAY CALIBRE SYNC Turn on the Content Server in Calibre (Mac, Windows or Linux) and Pageo finds it on your local network, or connect by address. Books come to your iPhone or iPad — and your reading position, finished books, ratings and highlights go back to your computer, into Calibre's own annotations. Download one book or the whole library in a tap. ▶ ALL YOUR CALIBRE LIBRARIES — EVEN WITH YOUR COMPUTER OFF Multiple Calibre libraries: browse one at a time or all at once, with separate progress for every book. Or open a Calibre library folder straight from iCloud, Dropbox or this device — no server needed. ▶ PICK UP WHERE YOU LEFT OFF With Pageo Pro, your place, bookmarks and highlights follow you between iPhone and iPad through iCloud — with or without Calibre. Just add the same book on each device. ▶ BUILT FOR CALIBRE POWER USERS Table view puts the columns you built in Calibre into a desktop-style layout — sort by any column, pin titles, jump with the A–Z rail. Search your whole library with Calibre's own search syntax, or search inside every book, even ones you haven't downloaded yet. Series, tags and the author sort you set in Calibre carry over. ▶ CONVERT ANY EBOOK PDF, MOBI, AZW, AZW3, FB2 and CBZ/CBR comics become clean EPUBs right on your device — no desktop, no extra apps. A PDF's footnotes move to the end of the chapter, a tap away from their number. Anything Pageo can't convert itself, it hands to your Calibre server. Share a web page from Safari and it becomes a clean EPUB on your shelf. ▶ READ YOUR WAY Any iOS typeface or reading aids like OpenDyslexic, Atkinson Hyperlegible and Lexend. Focus Text, word spacing and hyphenation in your book's own language. Text up to 400%, six line-spacing and six margin settings. Light, dark and sepia themes, page or scroll mode, page curl or instant turns, right-to-left languages. Tap a picture to see it full screen and zoom in. Highlights, notes and bookmarks — export your annotations to a single file. Pageo remembers your place in every book. ▶ LISTEN TO YOUR BOOKS Turn any ebook into an audiobook with built-in read-aloud: ten lifelike voices, 31 languages, fully offline after a single download. The page follows the voice, and every language gets a natural pace. ▶ FIND ANYTHING FAST Search inside the book you're reading or across your whole library. Your books, chapters, highlights and bookmarks show up in Spotlight, and Siri Shortcuts let you say "Continue reading in Pageo" or "Listen to my book in Pageo". Home Screen widgets keep your current book and reading streak in view. ▶ YOUR LIBRARY, YOUR CONTROL Import from Files, Dropbox, OneDrive or iCloud Drive. Organize by author, series, tags or collection. Nothing to read yet? The Discover tab offers free public-domain classics from Project Gutenberg in many languages. Your books stay on your device — no account, no lock-in. ▶ FREE WITH OPTIONAL PRO UPGRADE Pageo is free to use with ads. Pageo Pro unlocks read-aloud, the converters and iCloud sync, and removes ads. Try Pro free for 3 days. ▶ COMMON QUESTIONS Does Pageo work with Calibre? Yes — with the Content Server built into Calibre on Mac, Windows and Linux. No plugin or connector to install. Does my reading sync between iPhone and iPad? Yes — through iCloud with Pageo Pro, or through Calibre. Does my computer need to be on? For server sync, yes. For a library folder in iCloud or Dropbox, no. Does reading progress sync back to Calibre? Yes — position, finished status, ratings and highlights. Do I need an account? No. Terms of Use (EULA): https://visioncraft.es/pageo-terms Privacy Policy: https://visioncraft.es/pageo-privacy-policy
