Users have recommended another excellent ePub reader: Koodo Reader. It supports Windows, macOS, Linux, Android, and iOS, and there is also a web version (Koodo Reader is an Electron-based application), while the source code is available on GitHub.

Some features of Koodo Reader:

  1. In addition to importing books from the local device, you can import them from various cloud drives.
  2. It offers numerous font options that greatly enhance the reading experience.
  3. It responds very quickly to input.

Apart from higher memory usage and the time-consuming need to reload content with each setting change, it's nearly perfect.
