1SAFE is a mobile application that allows users to report, with just a click, dangers and threats to public safety as well as antisocial behaviour and urban decay. Using a system of geolocation, alerts are sent to all citizens found within a particular radius, or who have selected that area as being one of interest. Whoever receives the alert and is within visual range may confirm or deny the same alert thereby increasing or decreasing its reliability. This function is possible thanks to a patented algorithm. The app can be completed by including the various methods used by Public Authorities, which utilise a control panel to verify the alerts within their particular area of competence. 1SAFE has recently developed 1SAFEnet designed for the real-time monitoring of vulnerable people or those at risk. 1SAFEnet Protezione Totale is a virtual network available only to municipalities that have activated 1SAFE, which is designed to provide assistance to young women or the elderly travelling alone or waiting in dangerous places. 1SAFEnet Followme and Followme+ enables users to monitor the route of another 1SAFE user who is in an isolated place.
