Good, but could be better
I found it to be the fastest, less-prone-to-failure, free QR reader around; and I was loving it. But it seems to only support a weblink and it automatically tries to open it in Safari. Which is an issue, since QR Codes can contain texts or numbers (in which case it will manage to decode, but it will tell you they couldnt open the website -afterall, its not a website).
NeoReader automatically assuming that your QR Code is weblink is a no-no. But with support for text and other things (like links to youtube/google maps) itd probably be the best QR Code Reader around.
