Type 1 diabetes (T1D) afflicts approximately 154,000 people under the age of 20. Most people with T1D are diagnosed at a young age; their parents have to manage their child's condition. Eventually, the child must begin to take steps to transition to self-management. During the transition from parent to adolescent self-management, difficulties arise because adolescents may not be fully aware of, or want, to take responsibility for all the necessary tasks to successfully manage their T1D. Though there are other apps on the market to help with diabetes care, NONE do what the proposed app will do. The proposed self-management mobile app allows for monitoring the patients' T1D by linking their self-management information to their parents' cell phone, and thus also helps to bridge communication gaps. Prior research suggests that these are critical gaps that must be filled in order for successful transition in care to occur, the proposed app will help fill some of these gaps.
