Absolutely fantastic

When people say macOS apps tend to be better than their PC counterparts, this is what they’re talking about. The UI is intensely fluid, the program excedingly stable, all presented in a beautiful, fast package.

I can honestly say that this is one of the best applications I as a student have purchased, and I wholejeartedly recommend it to all of my peers who are looking for a comprehensive PDF reader, especally after how Apple shortchanged us with Preview in OS X 10.10.
