The SOS - Lei Maria da Penha application is a tool that helps women who have been victims of domestic violence to get help and protection. It has two main functions: one is to send an emergency message with the woman's name and address to the monitoring center and the other is to send an emergency message on the phone of the Maria da Penha Patrol team.

When the SOS - Lei Maria da Penha application is activated, a message with the woman's name and its address will be sent to the monitoring center and to the phone of the Maria da Penha Patrol team. This is done in such a way that if the woman has not already been registered, the registration form will be sent to the address indicated and the woman will be registered in the database.
