Sixteen-year-olds Connor Koehler and Max Greenwald wanted a stop watch that could start, stop, and reset without them having to look at their iPhone screens. So they built one. The app doesn’t look like a high school project. I’m hearing increasingly from young developers. As an old guy I’m always impressed by the gumption required to create a product when you are in high school. I’m equally amazed how it is even possible for a few teenagers to have a good idea and get it in front of a global audience.
