Quality OCR tool

Ive run through a good deal of OCR apps. Although itd be nice if I could upload documents, PDFs, etc. besides just images, this is particularly one of my favorites because it can read the text to you. Still trying to figure out the difference between this and the free app though? Paid $5 and I cant tell the difference? Still early though and I have to use it more.
