Sorry, I should have clarified.

I'm not against using QR codes. I just didn't realize that I could close the modal window, and thought that I had to jump through hoops to try out Sketch.

Given the amount of crap that can be found on the internet, I have a very low threshold for losing interest.

A better approach would have been to remind me later than I can scan a QR code to access the page on my mobile device.
