The document describes Blink, a band and mobile application that helps parents keep track of their children's locations both indoors and outdoors through GPS tracking, notifying parents if a child wanders out of a set range or if the band is removed from the child. The core value of Blink is to help take care of children and assist parents in doing so. The application allows parents to view their children's locations on maps, set meeting places, and send alerts to police if a child cannot be found.
