Did OP say they're Iraqi? People are sometimes new to a place, staying there temporarily, just want to know, or are asking for someone else.

Thing is, it's perfect for use on an e-ink device, which is what's it's primarily designed for. The desktop (Linux and Mac) and Android versions are just icing on the cake, and they all work the same and can sync reading activity between them. Tons of features, options for tweaking book layouts, plugins for integration with other services, some integration with Calibre, etc. It takes the "kitchen sink" approach and I love it. I've found spending the time to learn it to be really rewarding.
It's worth noting that for simple personal syncing with Joplin you don't need to run the full Joplin server — a simple WebDAV server is also an option.
