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.
