Tim Roberts is responsible for Fitbit’s design, including the website, mobile applications, desktop software, device interactions and APIs. Tim has spent the past 20 years crafting technology products as a founder or executive at such companies as Infectious, Twitter/Odeo and Bigstep. When not sedentary in front of a computer, he loves taking his Fitbit out for long runs on the hilly trails around the Bay Area. The Fitbit likes that. Today he’s showing us Fitbit’s newest offering, the Flex.
