iTunes link. The app is free, and my first impression of it is that it’s excellent. I think it’s a very creative and well-done interface. It doesn’t feel crippled or cramped to me. So far, I’ve used it for cropping, adjusting exposure, and adjusting color manually. It comes with some built-in color adjustment, “filters,” which I haven’t really been able to use yet, and you can also add frames like old-time photographs used to have.

I purchased Best Camera (iTunes link) a couple weeks ago for $3, and was very happy. But Photoshop.com Mobile has really depreciated its use on my phone.
