SafeTrek is a mobile application that can be downloaded by anyone for personal safety and security reasons. In times of need, just open the app and have it ready! If you feel uneasy or unsafe, keep a finger on the screen’s sensor, a process the company calls the “hold until safe” button. Removing your finger triggers a screen asking for a four-digit pin. If you enter the code, that’s your signal to dispatchers that you are safe. If you don’t, SafeTrek calls police and sends them to where you are using GPS. SafeTrek, a tech startup based in St. Louis, is an Arch Grants recipient receiving a $50,000 grant. To learn more about Arch Grants:http://archgrants.org.
