Horn is a program designed to quickly respond to any situation. When I open the program and click on the quick response button, all users, performers or the admin receive a push notification with the location and the person who clicked the button is displayed. This means that all users have been notified of the situation, and the performers need to go to the place of the event or urgently contact the company.
