Only reader.  UI is much simpler and not as nice as that of Calibre. Rendering is very slow: Resizing the window or changing font size takes ages.

It says:
– Version: 1.0.1
– Size: 5.1MB

but dowloaded is only a cca 300 kb exe. When you start it does not allow you to install the program without installing some third party webbrowser toolbars. I cancelled the installation procedure.

Very nice and good program! Could be a pearl.

The Library starts quite slowly. But it is possible to start the viewer only.
