Karl Becker 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.
