Doodling your greatest ever idea on a napkin is a little romantic, let’s be honest. A pen and paper are probably nearby, or you have an iPad or iPhone – who doesn’t? But the premise is still relevant, ideas pop up and you need to get the down. That’s where Napkin comes in handy, a newly released iPhone app that has a drag and drop design interface for you smartphone.

It was only a matter of time before someone released an app-building app for smartphones and while Napkin only lets you mock up design and interface ideas, it is still awesome. Essentially it is putting questions or design and userability in your palm, where you can assess it’s merit.

Created by Scott Savarie of Facebook, Napkin could make a splash in the design of apps in the near future.
