Let me start by saying I am an older (58), computer challenged kind of a guy. That said, I have found this program pretty easy to get around. I have been able to take a form my company uses and digitize it so I can actually read the responses people are giving me!! And to be able to store them electronically for future reference.

cost per document option
I would like it if you could have a price per document option. I very rarely need this app but when I do, it is very nice to have.I can't justify a monthly subscription but would pay $3 to $5/document. to use this app.
