Safety Button -- for emergencies

This is another what-will-they-think-of-next app. I continue to be astonished by the range of iPhone apps. Safety Button offers a big red button that will make you or your children safer when out and about. When you start the program, your iPhone starts tracing your steps on a server. If you press the button, the server will contact your chosen friend or a parent with a distress message containing your position and a panic message. The app costs $3.
