Josh Clark

Josh is the founder of Big Medium, a design agency specializing in connected devices, mobile experiences, and responsive Web design for the world’s most forward-thinking companies. Josh has written five books, including Tapworthy: Designing Great iPhone Apps for O’Reilly and Designing for Touch for A Book Apart. He speaks around the globe on what’s next for digital interfaces. In 1996, Josh created an entirely different kind of user interface: the Couch-to-5K (C25K) running schedule, which has helped millions of skeptical exercisers take up jogging. His motto is the same for fitness as it is for designing software user experiences: no pain, no pain.
