I needed nice circular QR codes with the client's logo inside. JoyQR can do that. But otherwise, it's very limited, the vCard is not white-labeled as advertised, and I see absolutely no product evolution for over a year. The deal with ElkQR here on AppSumo honestly seems like a much better option: more features, more power, and regular small updates that demonstrate the product still receives attention from its founder. Of course, I'll edit this review if things suddenly change, but as of the date I'm writing this review, that's what I can say about it.
