Decent app, irritating spam – SwiftScan - Document Scanner Review

This app follows one of the most irritating design paradigms ever: any time you click a button to do something, a screen pops up telling you you can't do that unless you pay. Basically it's one giant piece of adware for... itself? Scanning seems to work, but I'm not going to give this company 8 bucks just to find out more. Bleach.
