We needed a single QR code for our advertising materials. Rather than having two or three QR codes for all stores, we developed QRUnity to have a single one. Links can be updated dynamically, so any link changes will not affect your already deployed QR codes.
It's totally free.
Hope you enjoy
But if this goes on any "permanent" material (eg. printed on posters and such), it's nasty that the link would be on a domain controlled by someone else. Someone whose business model could change at any time, who could shut down and the links wouldn't work, or worse, who could start redirecting to malware.
My advice: Decentralize this by offering it not just as a service, but by licensing it to companies that want this on their own servers. I suspect some would pay a decent price for this.
Those are really valid concerns, we'll surely take it into consideration. We will pack it for download soon. First lets see if we're the only ones who hate multiple QR codes =)
I, and I'm being sincere and not at all snarky here, would be curious to see if people still use QR codes. Is this something used more frequently outside the US? I can't remember ever seeing a QR code and thinking "I'll go download an app and scan that and see where it goes".
I really am curious. Do you have metrics to share?
We just launched this so I don't have valuable metrics yet (can publish after a month or so). However, I can tell from experience that QR codes are still "in" for most of Europe. We even had clients asking us for QR codes to be printed in brochures etc, even before we created app store app.
One reason that I coded this site is to send away QR codes asap and figure out app store links later.
Yes they change name of the app last minute =)
