Leaf: EPUB Library2026.6 - App Store

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, organize them your way, and keep everything in sync with iCloud.

READ YOUR WAY

Make every book comfortable to read. Choose from carefully selected fonts-including accessibility-friendly options-and fine-tune the font size, line height, margins, letter spacing, word spacing, and alignment.

Choose from a collection of color themes, follow your device’s appearance automatically, or give individual books their own settings. A configurable reader footer can show page count, percentage, chapter progress, chapter title, or book title.

A LIBRARY THAT FEELS LIKE YOURS

Create custom shelves and let Smart Shelves automatically gather books that are In Progress, Unread, Completed, Did Not Finish, or downloaded to your device.

Browse by author, series, and genre; search and sort your collection; and edit titles, authors, covers, descriptions, publication details, and more.

Rate books, mark the ones you loved, 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, settings, and reading progress available across your iPhone and iPad. No separate Leaf account is required.

Download books for offline reading, remove local copies when you need space, and return to your current book from the Home Screen widget.

FIND YOUR NEXT BOOK

Connect to a self-hosted Grimmory library, browse Project Gutenberg through the built-in Source, add other compatible OPDS sources, or import EPUB files from Files.

Leaf also includes a small collection of beautifully produced public-domain classics, so you can begin reading immediately.

For readers who also use KOReader on e-ink devices, Leaf can sync reading progress with a compatible KOReader sync server.

BUILT FOR IPHONE AND IPAD

Leaf is designed for every screen it runs on: a focused reading experience on iPhone and a spacious library on iPad. Your books feel at home wherever you read.

Leaf currently supports DRM-free EPUB books.
