LiBook is a personal reading app that brings all your ebooks together in one place. Import your EPUB, PDF, and TXT files, organize them into your library and collections, and pick up right where you left off. With support for table of contents, search, bookmarks, and highlights, you can easily find what you need—even in long books—and come back to it whenever you want. With iCloud, your reading experience continues seamlessly across your devices. Your books, highlights, and reading positions are stored in your own iCloud and stay in sync across devices using the same Apple Account. If a book isn't currently stored on your device, a download indicator appears on its cover, allowing you to download it whenever you need it. You can also download an entire collection in advance for offline reading. When you need to free up storage space, you can remove books from your device while keeping them safely stored in iCloud. Keep track of characters while reading novels and long-form books. In EPUB and TXT books, you can select a character's name and save it as a character card with your own notes and descriptions. You can also see where a registered character appears throughout the book, making it easier to keep track of characters in stories with large casts. Customize your reading experience to suit each book and your preferences. For EPUB books, you can adjust font size, line spacing, paragraph spacing, margins, themes, and more. For PDFs, you can configure screen fitting, scrolling direction, and page-turning behavior. When reading isn't convenient, listen to your books with TTS. LiBook supports play, pause, previous and next navigation, adjustable speech speed, and a sleep timer, so you can listen comfortably whenever you want. ### Key Features * Import EPUB, PDF, and TXT files * Organize your library and collections * Manage book covers * Sort collections by recently modified, newest, name, or number of books * Save reading position and progress * iCloud sync for books, highlights, and reading positions * Download entire collections for offline reading * Remove books from your device while keeping them in iCloud * Table of contents, search, bookmarks, and highlights * Character registration and character cards for EPUB/TXT * View character appearances throughout a book * EPUB reading customization * PDF viewing settings * TTS playback and sleep timer * Multilingual UI support LiBook focuses on the reading experience rather than complicated features.
