Karl has had an app on the iOS App Store since it opened, creating Car Care to help him track his car’s gas mileage. Since then, he has co-founded a company called Third Iron, which creates the world’s most popular journal reading and engagement service, BrowZine, which has a full-featured iOS app, as well as Android and responsive web app. When Karl is not in front of a computer at home, he likes to be in front of a computer while traveling… with occasional looking up from the screen.
