A free personal-safety mobile app allows friends to virtually walk you home at night. The Companion app, created by five students from the University of Michigan, enables users to request a friend or family member to keep them company virtually & track their journey home via GPS on an online map.
The user can send out several requests to different phone contacts in case people are not available to be a companion or not with their phones at the time. Those contacted then receive an SMS text message with a hyperlink in it that sends them to a web page with an interactive map showing the user walking to their destination. If the user strays off their path, falls, is pushed, starts running, or has their headphones yanked out of their phone, the app detects these changes in movement and asks the user if they're OK.
