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. Your whole library on your iPhone or iPad in seconds — and your reading goes back to Calibre. ▶ 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. ▶ 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. 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. 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. Start listening from the library, right where you left off. ▶ 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 and the converters, 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. Can I view my Calibre library without downloading everything? Yes — browse covers and metadata for every book, download only what you want to read. 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 ——— Pageo is made for readers who use Calibre.

ReceptionRating · Positive reviews · Number of ratings

Calibre ebook holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Calibre ebook has 11 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 0% of Calibre ebook's written reviews are positive against 33% of Moon+ Reader's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Calibre ebook ships an update every 10 days, Moon+ Reader monthly. The most recent releases landed on October 10, 2026 and October 11, 2026 respectively.
