Josh Clark is a designer specializing in mobile design strategy and user experience. He's author of the O'Reilly books "Tapworthy: Designing Great iPhone Apps" and "Best iPhone Apps." Josh's outfit Global Moxie offers consulting services and workshops to help media companies, design agencies, and creative organizations build tapworthy mobile apps and effective websites.
Before the interwebs swallowed him up, Josh worked on a slew of national PBS programs at Boston's WGBH. He shared his three words of Russian with Mikhail Gorbachev, strolled the ranch with Nancy Reagan, hobnobbed with Rockefellers, and wrote trivia questions for a primetime game show. In 1996, he created the uberpopular "Couch-to-5K" (C25K) running program, which has helped millions of skeptical would-be exercisers take up jogging. (His motto is the same for fitness as it is for user experience: no pain, no pain.)
