Overview

A closer look at Yomu EBook Reader.

Yomu is an ebook reader for files without digital rights management. The listing names EPUB, MOBI, Kindle formats, PDF, and comic archives, and lets readers adjust fonts, text size, themes, and page or scrolling layout. Books can be imported from other apps, cloud drives, OPDS catalogs, or Calibre.

Yomu does not sell a reading catalog in the listing; it is designed for opening books the user already has or can download from sources such as Project Gutenberg. Notes and annotations are available for supported formats. The free version includes basic reading features but limits the number of documents and can show ads. Yomu Pro removes the document limit, removes ads, and includes its iCloud-based cloud library.

Check that ebooks are DRM-free and that you have the right to download or transfer them. Pro billing terms and current prices should be reviewed in the App Store. We have not tested format compatibility, annotation sync, or imports from every provider; maintain a separate copy of original book files.
