5 stars: Wish it let me us the cloud sync like acrobat reader but am willing to pay for that feature. Background colour option helps put leas eye strain
4 stars: Nice application but you can improve the page switching feature
3 stars: The problem is if you try to use file explorer to open files with this app it doesnt know what to do, it has its own library folder you have to shove files into. The interface is unintuitive and there is no option to change the library directory. As a reader it works just fine, it just needs a little help. It struggles a bit with font sizes sometimes but litterally every Epub reader does.
