6. Circle of Six

Circle of Six is a free program for iOS and Android users. It is an award winning program that helps you to stay safe by being able to connect you up to as many as six trusted contacts when you are out and about in a strange area or even just walking on campus. You can feel safer because you have instant access to a pre-programed message to have any of your six contacts come and get you. They will know exactly where you are due to the GPS integration of the program that works with your phone. It will also let you call national and local emergency hotlines if you are in a really bad situation and need help from the proper authorities. If you want to feel safe, then get this free program for your iPhone. Plus, if you have less than six people to sign up as contacts, you can still us it with no problems.
