There was a thread somewhere on APUG the other day about this: https://itunes.apple.com/us/app/id374359605?mt=8
I haven't downloaded it yet but it looks pretty sweet! And apparently it was designed by one of the APUG members so it's always good to support our own.
Maybe when it is updated for the iPhone 5 I will take another look at it.
