Read full description

Welcome to your Own Shelf. Import any EPUB you own and press play. The text rolls like a teleprompter or the credits at the end of a film, so you can sit back and read hands free. SET YOUR OWN PACE Set the roll anywhere from 60 to 450 words per minute. Tap to pause, tap to resume. A floating HUD shows your progress, time remaining, and words per minute, then tucks away so you can focus. YOUR LIBRARY, ORGANISED Import EPUBs you own, including public-domain books from libraries such as Project Gutenberg, and they appear in a clean grid with real cover art extracted from each file. Press and hold to remove a title. Pull down to refresh. Every book remembers exactly where you left off. CHAPTER NAVIGATION Open the chapter sheet to see the full table of contents, grouped into Front Matter and Story. Tap any chapter to jump straight there. A "Skip to start of book" button appears automatically when you're in a preface or copyright page. BOOKMARKS Tap the bookmark icon to save your spot. View all bookmarks with percentage and age, jump back instantly, or delete ones you no longer need. Bookmarks are stored by character offset so they survive changes to font size. READING STREAKS Build a daily reading habit. Own Shelf tracks your streak with milestone badges at 3, 7, 14, 30, 100, and 365 days. A weekly chart shows your reading activity at a glance, and a warning style nudges you when your streak is about to break. MAKE IT YOURS Choose from Light, Sepia, or Dark themes. Pick Sans, Serif, or Mono fonts. Step text size from 14 to 56 px. All preferences persist across your entire library. PRIVATE BY DESIGN Everything stays on your device. EPUBs are opened and parsed entirely on your iPhone. Own Shelf has no server and makes no network requests, so your files and reading never leave your device. Your library, bookmarks, reading position, and preferences are all stored locally. No accounts, no cloud sync, no tracking. Your reading is your own.
