This project describes the design and development of a system that will help to increase safety and security using cell phones. This system has two main components: a master phone application to assist people who need to take care of their loved ones, and a slave phone application to provide help to care-recipients who need attention from their caregivers. This system applies location awareness (GPS), awareness of social activities (communication activity and proximity with close peers), and peer-to-peer data communication as its core technologies.
