It's amazing how much scarier the world is when you're by yourself. A parking lot, a city street, even your own home: Each one just seems more dangerous when you're alone. You're just more vulnerable without backup. That's why thousands are flocking to this new app that gives you a companion to walk you home.
The app, for iOS or Android, is called Companion, and it was created by students at the University of Michigan. With the app installed, you can request that a friend or relative keep track of you virtually on your way home using GPS. The other person doesn't even need to have the app installed.
The companion then gets a text message with a link to a website where they can see you walking to your destination. If you go off course, fall down, start running or the headphones are suddenly removed, the app asks if you're OK. You have 15 seconds to press a button saying you're all right.
If you don't push the button, the app starts playing loud alarm noises, and you can call police by pushing a button. There's also a button to just alert the app that you're nervous. That information is compiled for security and law enforcement.
We think this app is fantastic, and it's free. If you've used the Companion app, let us know what you think of it in the comments below. Here's a video showing how the app works.
