University of Michigan students have created a new mobile and Web app to keep students safe.
Danny Freed, a senior business student at U-M, is one of five students who launched the app Companion -- a peer-to-peer safety monitoring service that lets people track your GPS location as you walk from place to place. "You can use the app with anyone in your contact book and they don't have to have the app. You punch in the address or place you're headed and notify one or several friends that you're headed to that place," Freed said.
