A new app called "Companion" makes sure that you don´t walk home alone at night.
Before setting off on a journey, users type in a starting point and destination. A designated "companion" can then track the phone´s GPS on a map. The user is also given the option to 911 from within the app.
"It makes it very easy to call 911, and it also has a feature where you can say I´m feeling really nervous," Newyorker.com editor Nicholas Thompson explains. "Companion" was created by University of Michigan students.
