Hi @crazydani One of the most important things of the D.A.D. 2 are the Bluetooth and GPS technology "Crowd Alert" offers a very important extra layer for personal security, through which the user can send a message "I AM IN DANGER" by just touching the black button. This alert comes with a picture of the user and the GPS location of the same, which is received by other users of the application who are volunteers from the Network of Heroes that are near to the place!
