How do I read NAS / Calibre ebooks on iPhone?

How do I read NAS / Calibre ebooks on iPhone?

When EPUB and PDF already live on a home computer, the question is rarely “where to find books”—it is how to open the same library on the commute with progress intact.

Pick a path, then a tool

  1. Few books: import via Files and read offline.
  2. Books on NAS / cloud: enable WebDAV or SMB and browse folders from the phone.
  3. Calibre / OPDS already running: connect a private-library reader—less copying.

Files stay with you; the app opens and organizes them. That is not the same as an online bookstore.

What ShuYu solves

ShuYu is a private ebook reader for iPhone / iPad: local import plus WebDAV, SMB, OPDS, and Calibre. No built-in store; books are not uploaded to the developer. Optional WebDAV sync for progress, notes, and settings; Face ID can lock the app.

Unlock advanced features when you rely on remote libraries or multi-device reading. For a few local files, start local.

Formats and expectations

Common readable directions include TXT, EPUB, PDF, plus Markdown, HTML, FB2, RTF, DOCX, CBZ, and more (check the current build). MOBI / AZW are usually better converted to EPUB or PDF first.

FAQ

What is ShuYu?

A private ebook reader for your own files and NAS / OPDS / Calibre—not an online bookstore.

How do I connect Calibre / OPDS?

In the app: add a private library → pick the type → enter address and account → browse, then download or stream. Confirm the service is reachable from the phone first.

How does progress sync?

Use your own WebDAV folder for progress, notes, highlights, and settings. Synced reading data is not the same as every book file existing on another device—check both when you switch phones.

How does it split with ManYue?

Ebooks → ShuYu; manga / CBZ libraries → ManYue.
