FRE SOS is an app that provides you with a button to request help when necessary, which is linked to your neighborhood's lobby. It uses multiple location features like GPS and wi-fi to precisely gather informations regarding your current location at that moment.

But how does it work?

If you are facing a dangerous situation at home, a robbery, for example, and you made sure you have the right amout of time to hide yourself with your phone, you can simply open the app, tap on the screen and, in a matter of seconds, it will inform the lobby of your neighborhood that something is going on at your current position.
