I come home from work very late at night, and as parking is limited in my neighborhood, sometimes I park as much as half a block or more away. I notify a friend that I know is up and he accompanies me virtually until I get home. Then I notify him that Im home and safe. I feel so much safer knowing there someone that will know if I have a problem and call the police, although the app itself will also call the police. Important for anyone who is walking alone and feeling a little nervous about where they are or the time of night. I told all my friends to make sure their kids have it so their kids can let them know when theyre feeling a little nervous about walking somewhere etc. no, the app is not always on and following them around! They have to turn it on, notify the parent or friend, and then turn it off when they get to their destination. I think some people think that its watching them all the time; it only is when you want it to. I have friends in other countries that have their kids use it and it works well for them as well.
