"We'd like to thank SYDCON for their generous involvement in developing the Teen Sleep Tracker iPod application for our federally funded National Institute of Health research project aimed to help adolescents experiencing problems related to sleep timing and duration. Dave and his company, SYDCON, donated many hours of their time and resources to tailor make our application, which is designed to collect self-reported sleep timing and daily activity responses from study participants. Throughout the development process, Dave provided valuable feedback and was quick to respond to any questions or concerns we had. We couldn't have developed the app without help from Dave and sincerely thank him and his team for all their hard work."
