Anyone Use 645 Pro ?

This is my primary camera app on my iPhone 4S, and I am very happy with it.  It will shoot higher quality jpeg files than other camera apps, and has many other features as well.

Snapseed is my image processing app of choice, mostly because I think the developers really "get" how to best use the iOS user interface in terms of simplicity and elegance.

I have a number of other photo apps, but those two area my favorites by far.
