Book Isle

Book Isle is an e-book reader designed for personal private libraries. You can connect your iPhone and iPad to your own NAS, WebDAV, SMB, OPDS, or Calibre library, import, browse, search, download, and read local and remote books. The app does not provide an online bookstore, does not host or distribute book content, and your book files are still managed by your local device or your own private library.

Main functions:

• Private library connection: Supports WebDAV, SMB, OPDS, Calibre Content Server, and Calibre metadata.db.
• Multi-format bookshelf: Supports the import, management, and reading of TXT, EPUB, PDF, Markdown, HTML, FB2, RTF, DOCX, CBZ, and common audiobook formats; MOBI, AZW, AZW3, CBR, DJVU can be imported, managed, filtered, and synchronized. It is recommended to convert them to EPUB, PDF, or CBZ for reading.
• Local reading experience: Supports bookshelf grid/list, sorting, tagging, rating, reading status, full-text search, bookmarking, notes, highlighting, book excerpt cards, and reading statistics.
• Remote reading and downloading: Browse private libraries from NAS, OPDS, or Calibre, download or stream supported book formats on demand.
• Private synchronization: Synchronize reading progress, book metadata, notes, highlights, tags, reading statistics, and reading settings through the WebDAV directory you have configured.
• Privacy and security: No self-built account system; supports Face ID app lock; book files will not be automatically uploaded to our servers due to synchronization function.

ShuYu is suitable for readers who already have NAS, Calibre, WebDAV directories, or OPDS book sources, allowing them to manage their private book collections with a quiet and reliable reader.
