Photo iPhone apps like photoshop?

What are some really good Photography apps for iPhone where you can edit pictures really cool? I don't mean ones that just change the hue and where you can crop the pictures. But i've seen pictures where there's like someone standing in hands and edits like that that look like they were done on photoshop but the creator says that all she uses is apps? Anyone have any good ones?

Best is Photoshop touch by adobe. But it's for iPad. There's no cool app like Photoshop for iPhone and android.
