eBook Manager for iOS puts your whole e-book library in your pocket — the companion app to eBook Manager for Mac. YOUR LIBRARY, EVERYWHERE Everything syncs through your personal iCloud account — no accounts to create, no third-party servers. Books, covers, metadata, ratings, collections, reading lists, and reading positions stay identical across Mac, iPhone, and iPad. Download any book on demand; a quick filter shows what's already on your device for offline reading. A READER THAT GETS OUT OF THE WAY Built on Readium, the open-source EPUB engine. Tap the edges or swipe to turn pages, tap the center to hide the controls, and fine-tune fonts, text size, and light, sepia, or dark themes — your reader settings sync between devices too. Start a chapter on your Mac and your iPhone offers to continue from the same spot. PDFs open in a full PDF view. BROWSE BEAUTIFULLY A cover grid or detailed list, live search across titles, authors, series, and tags, and instant filters for favorites and reading status. On iPad, a three-column layout puts your sidebar, library, and book page side by side. ORGANIZE ON THE GO Edit metadata, set ratings and reading status, favorite with a swipe, and browse the collections, reading lists, and smart lists you built on the Mac — edits sync back instantly. EVERYTHING ELSE YOU'D EXPECT • Statistics and a yearly reading goal • Series completeness — see which volumes you're missing • Online metadata and covers from Google Books, Open Library, and Hardcover • Import EPUB and PDF files directly on the device • A free starter set of classic literature to try the app with • Tidy Up repairs defective EPUB files right on your phone eBook Manager for iOS is a native SwiftUI app — fast, light, and at home on iPhone and iPad.
