Program's author here: the point of this app is to simplify the test and debug of the QR code itself. Although all reasonable people think they are pointless, countless graphic designers are forced to incorporate QR codes into their otherwise beautiful works. This app (and it's just an app, not an application) lets them quickly test variations.

OK fair enough. I suppose if QR codes must exist, then the lives of designers should be made less painful.
