They say there's an app for everything, including creative apps. No matter how crazy that sounds, with a brand new app called Napkin you can create complex interactive app mockups directly on your phone.
You no longer need a desktop computer to put together quick design comps. Developed by designer Scott Savarie, Napkin features a straightforward touch-optimized interface that lets you add shapes, labels, icons, and photos. All objects can by moved and resized by dragging as well as grouped as layers for easier manipulation.
Napkin comes with some advanced functionality that we're surprised to see in a mobile app. Even more so when we consider the fact that the creator of the app took only one iOS development class.
