I am looking for an APP for iPad that I can draw. One that can provide dimensions. I have always wanted to use sketchup on my computer but just don't have the time to learn how to use the software. I always end up with graph paper and pencil.

Really, if there was just an App that had graph paper and could automatically add dimensions , that would helpful. Just something fairly simple. Even a more advanced program would work if it was intuitive and you could do basic stuff easily and just kind of learn more about it as you go along, and not have to take a 40 hour (figurative) class before you use it.
