Simple eReader is an Android e-book viewer designed for comfortable reading of Epub novels and comics/image collections compressed in zip/RAR formats.
The key features of this app are the "simple and faithful display of Japanese Epub files" and "stress-free reading of files over the network."

[Key Features]
◆ Comfortable Network Reading
Supports the SMB protocol, allowing direct access to book files in shared folders on a NAS or PC.
Because it loads only the necessary data without downloading the entire compressed file to your phone, you can start reading smoothly with no waiting time, even for large archive files.

◆ Faithful Display of Japanese Epubs
It faithfully renders expressions unique to the Japanese language, such as vertical writing, Ruby (furigana), and punctuation marks. You can finely customize font type, size, line spacing, margins, and background colors (Dark mode, Sepia, etc.).

◆ Comfortable Image Viewer
Smoothly displays comics and art books compressed in zip or RAR formats. There is no need to extract files, allowing you to focus on reading.
Features include:
Intuitive zoom via long-press
Page navigation by selecting specific files within archives
Switch between Right-to-Left / Left-to-Right binding

◆ Others
Library function: Manage local and network files via tabs. Automatically retrieves cover images for a graphical list display.
Resume reading: Automatically saves the last read page so you can resume immediately next time.
Supported formats: Epub, zip, RAR, CBZ, CBR, Image folders (JPG, PNG, GIF, WebP, etc.)

[Please Note]
* This app only supports DRM-free (unencrypted) Epub files.
Please note that files purchased from e-book stores such as Kindle or Kobo, which are protected by DRM (Digital Rights Management), may not be viewable.
