Applications which run on mobile devices have special user interface requirements. I think Apple did a great job introducing innovative controls on the iPhone/iPod touch platfor
I tried Mirabyte and SlideUI. I downloaded and played with both of them. The SlideUI controls (1.6) are really good, and I have to say I am impressed. I'm setting up a student license from them now. I would recommend this for anyone looking for an easier way to make a nice looking app without having to create your own designs and controls.
