Based on how much rubbish is in the App Store, it is shocking to me – but getting that first approval can be really brutal. Took me well over a month last October/November as it kept getting rejected for things that I considered very much outside the purview of App Store review†, and this was for a simple and straight forward client portal for our company. If I didn't know better, I'd think they don't want you building free apps.

†my favourite was that on one of our menu screens the bottom button was slightly obscured by the tab bar at the bottom, so of course that was a failure. I'm not sure when they started this sort of semi-QA type of service, but I suspect no one asked for it.
