Mostdesigners will doodle when they are bored. The sketch is the first step in the creative process. It is easy as well as free-flowing when one sketches on a paper but the major challenge for most designers is to turn them into work that is reusable. They need to transfer the ideas from paper to digital and this is done by scanning, tracing or by recreating a digital version of their sketch.
Digital platform,however,will not be a paper killer. The benefit of using the mobile app to draw is that you can sketch your mock drawing digitally and easily turn it into a usable Photoshop, design file or an illustrator. The software matches the iterative process of paper and also saves the designer a lot of time by eliminating the requirement to redo the work from the beginning on the desktop.
