Fish Eye App?

[Barders]

Hi,

I can't afford a Fish Eye lens for my camera at the moment, so thought I would have a look to see what I could do with the iPad. But the ones that are coming up on the iTunes sites are either unrated or have a bad review.

So I wondered if anyone had found an app that was good for messing about with fish eye please?

Many thanks in advance.
