Fastest one there is!

Its also the only one I could get to work with an iPod touch. I guess since they dont have autofocus the other qr apps have a hard time. My only complaint is that the UI doesnt support retina. I also dont like the cartoony icons. Something a little more Apple-esque would be nice. Other than that its great!!
