User blog:Kimiyosis/Tablet Drawing Apps?

So, I've been told that drawing on the tablet is better than on paper. So...which app should I download and use? I've tried a few, but either they don't allow me to do layers, or they have a fountain pen style of drawing(where the line gets fatter or thinner, depending on the direction being drawn).

So, any suggestions? Ah, and I'm on the IPad(4th), if that's any help!
