Most entrepreneurs would tell you that being able to turn sketches into functioning prototypes is very important. If you have some design and coding skills, you may be able to pull it off fast. Apps such as AppSeed make the process a lot easier. It is a handy app that speeds up how you create and share your ideas. It captures your sketched design, turns them into a number of UI elements, and lets you run your prototype on your mobile device.
You will be able to share your prototype with others and edit it using professional software suites. All you have to do is sketch your designs on paper, capture them, test your work, and edit it to perfect it. A pretty hot idea if you ask us.
