XnView MP stands for Multi Platform = it is available for Windows, Linux and MacOS. It is a continuation of the older XnView Classic. In my opinion it is a great alternative to Windows photos app or any Linux image viewer that comes preinstalled. I even think it is an alternative to IrfanView. It is really fast and simple to use, supports more than 500 image formats, has built in folder browser, image converter, editor... AND MORE!
I have a problem syncing my Pixave iPad library with the desktop version. After several messages to the developer over the last few weeks I have had no reply. Rather a shame as I have been using Pixave for many years.
