The Bull Horns app comes with an in-app

When you press the Woza Lite app panic button (or just give your phone a hard shake to activate a panic), you are connected with either your security company's control room, the local SAPS police station or whoever you want to connect with telephonically in an emergency.

At the same time, the app automatically creates sms notifications that are sent to the numbers that you specified as emergency contacts when you registered. These sms messages contain a link that shows your real-time location (your phone is tracked as long as the panic alert remains open).
