Give your books a home of their own. Leaf brings beautiful EPUB reading and thoughtful library management together on iPhone and iPad. Import the DRM-free books you already own, make yourself comfortable, and pick up where you left off. READ YOUR WAY Choose from carefully selected fonts, including accessibility-friendly options. Adjust your reading theme and font size, or use Leaf Pro to import your own fonts and fine-tune typography and book formatting. Give individual books their own settings. On iPad, choose one column, two columns, or an automatic layout that adapts to the space available. Customize the reader's header and footer to keep the book and progress details you care about in view. KEEP THE PLACES THAT MATTER Save bookmarks as you read and return to them from the book's contents. See the surrounding text to remind yourself why you saved a place. With Leaf Pro, add personal notes to your bookmarks. A LIBRARY THAT FEELS LIKE YOURS Browse by author, series, and genre; search and sort your collection; and edit titles, authors, covers, descriptions, and more. Smart Shelves gather books by reading status and download availability. Leaf Pro adds custom shelves for your own collections. Rate books, mark favorites, and write down your thoughts when you finish. Leaf remembers reading time, completion dates, and the books you have finished this year, then helps you choose what comes next. PICK UP WHERE YOU LEFT OFF Optional iCloud sync keeps your books, library details, and reading progress available across your iPhone and iPad using your own Apple Account. Keep a local library if you prefer. No Leaf account is required to import and read your books. Download books for offline reading, remove local copies when you need space, and return to your current book from the Home Screen widget. Read on an e-ink device too? With Leaf Pro, exchange reading positions for matching EPUBs with a compatible KOReader Sync server. Compare chapter titles and text previews before choosing a position. FIND YOUR NEXT BOOK Import EPUBs from Files or send them to Leaf from another app's share sheet. Browse and download public-domain books from the built-in Project Gutenberg Source, or start with the included classics from Standard Ebooks. Connect your own OPDS, Grimmory, or BookOrbit Sources and browse your libraries in Leaf. Downloading from your own Sources requires Leaf Pro. START READING FOR FREE Import and read your DRM-free EPUBs, save bookmarks, and use iCloud sync without a subscription.

Verdict
The clearest difference is in-app purchases: Calibre 2 at none against Leaf's 1. Calibre 2 also leads on iOS requirement (15.0 vs 26.1). On price, ads and device support there is nothing between them.
