Finding cool iOS startups

So.. I've been a long-time android user, but am considering getting the iPhone 5 mostly just due to the fact there are so many early-stage apps I'm missing out on.

I've come across a couple of these apps in the past, but didn't really bookmark them or anything (since I wasn't an iOS user :P)

Just wonderin'- is there any sort of place online where I can find cool, recent iOS startups?
