SafeTrek is a mobile personal safety app that allows you to protect yourself without the heavy commitment of calling 911. You launch the app and hold down the safe button and when you feel comfortable you release and enter a pin. If you need help, you release the button and the police will be notified of your location, name and emergency. The app is currently available for iOS and Android. STL TV Live, host Sarah Bernard, gets the scoop from SafeTrek CEO, Zach Winkler.
