Terrible - Blurry and Buggy
I guess the Foxit people didn’t develop their app on a mac with a Retina display, because everything is blurry — including the text in PDFs! Just to be clear, the text is crystal clear in Preview, so it’s Foxit and not the PDF.
It’s also buggy. For example, when you zoom in so that horizontal scrolling is necessary, scrolling via the trackpad doesn’t work. Instead, you have to use their horizontal scrollbar with the mouse.
It also doesn’t seem to support basic reading features, like text reflow so that you can increase the font size and read a document without having to scroll horizontally back and forth for each line of text.
