University of Missouri students have designed an app to improve campus safety by eliminating the process of calling for emergencies.

Individuals who feel they are in danger can open the app, Safe Trek, and press the shield icon. When they let go of the icon, they have a few seconds to type in their four digit pin. If they fail to do so, the local police will be dispatched within 50 seconds to their coordinates.

Safe Trek founder Zach Winkler said he hopes to use the app’s data to help make communities safer and improve the feeling of public safety.

“We had done a bit of research on [safety call boxes], and found that over the course of 10 years, they had been used twice for real emergencies and only one police report,” Walker said. “The app is directly connected to the emergency call centers. It’s like a home security system that travels with you.”

Safe Trek costs $2.99 a month and has about 250,000 subscribers.

“This is the same service that ADT provides for $60 per month,” Winkler said. “We do it for $2.99, and it goes wherever you go. We aren’t greedy people, but we need to keep the app working.”

The app was originally developed for college campuses, but is now connected to 9,000 emergency call centers across the country, Winkler said. Safe Trek can be purchased at the Android and Apple stores.
