I'm sure you are pretty bitter about your project getting crapped on here, but it should have been a foregone conclusion. Someone, anyone, could have explained this position any time before you ran this thing all the way to the product stage and started announcing it. Whatever process you followed to get here appears to have been flawed; either you took too little advice, you took poor or unqualified advice, or you refused to accept valid criticisms.

If you want to wow this crowd with something as hackneyed as QR codes you're gonna have to do stuff that's on a different level[1]. Make that into a $10/month product bundled with all the bells and whistles of a mature marketing tracker and you might have something. I want to be clear that there's nothing wrong with what you have made, but the way you have positioned it to have more value than it actually offers. What you have today is the answer to a homework assignment, not a product, and it would be better received if you did not force it to wear a costume.
