Your library, your shelf, your reading habit. Leaf & Spine is a calm, distraction-free home for your EPUBs, PDFs, comics and audiobooks. Arrange them on a 3D bookshelf, read with highlights, notes and drawings, listen with the screen off, and watch a daily reading habit take shape. Read for free, or upgrade to Premium for stats, focus sessions, backups and your own servers. BRING IN YOUR BOOKS • Read EPUB, PDF, CBZ and CBR, and listen to audiobooks. Audiobooks require Premium. • Add a whole folder at once, or pick files yourself. • Discover free public-domain books and audiobooks from Project Gutenberg, Standard Ebooks and LibriVox. • Connect your own server (Premium): Calibre, Calibre-Web, Kavita, Komga, Audiobookshelf, or a WebDAV folder such as Nextcloud or a NAS. Browse it, search it as you type, and download books to read offline. READ YOUR WAY • Highlight, take notes, draw with pen, pencil and highlighter, and look words up in the dictionary or translator. • Listen: the page is read aloud with the sentence lit up, using natural voices made on your device, and an EPUB that comes with a recording plays the narrator. • Focus mode for reading a sentence at a time, and a reading ruler. • Presets, typefaces (including Atkinson Hyperlegible and OpenDyslexic), heading styles and page-turn speed. Premium readers can import their own fonts. AUDIOBOOKS THAT KEEP PLAYING • Keep listening with your phone locked or while you use another app, with play, pause and skip on the lock screen. • Chapters, bookmarks, notes, speed and a sleep timer that works with the screen off. ORGANISE YOUR SHELF • A 3D bookshelf with categories, sub-categories, tags and series, sorted and grouped by author or series, with bookends you can fold into a box set. • Spines take their colour from each book's cover, or customise spines, patterns and covers yourself. • A page for every book: progress, the next in its series, description, chapters and your marks. • Fix a book's details, or fill them in from Open Library (Premium). • The Notebook gathers every highlight, note, drawing and looked-up word from your whole library, and one search covers it all. BUILD A HABIT • Goals in minutes a day or days a week, reminders at a time you choose, and streak freezes so one missed day doesn't erase months. • Home follows the series you are reading, and finishing a book offers the next one. • Home screen widgets with your current book and a highlight worth rereading. • Premium stats: time read and listened, pages, chapters, books finished, genres, highlights and words looked up, by week, month, year or all time. FOCUS SESSIONS (Premium) • Set a timer and read inside an immersive environment: a fireplace, a beach, a waterfall or a rainy window, each with its own ambience and music, which keep playing with the screen locked. YOUR PLACE, EVERYWHERE (Premium) • Back up automatically to iCloud or Google Drive, and keep your place across your devices. • Sync your progress with Audiobookshelf, Komga, Kavita and KOReader. PRIVATE BY DESIGN • No account or sign-up needed to start reading. • Your books, highlights, notes and progress stay on your device. Backups go to your own iCloud or Google Drive, never to our servers. • Six themes, light and dark (two free), and the app in English, French, German, Italian, Spanish and Portuguese. PERFECT FOR • Students who highlight, draw and track study time. • Fiction readers who want EPUBs and audiobooks in one place. • Comic and manga readers with CBZ and CBR collections. • Anyone with a Calibre, Kavita, Komga or Audiobookshelf library. CONTENT NOTICE Leaf & Spine does not sell or host books. Discover lists free public-domain titles from Project Gutenberg, Standard Ebooks and LibriVox; everything else is your own files and your own servers.
