A community security app that launches push notifications as alerts in different roles can be a very useful tool for crime prevention and increasing security in the community. This application would allow users to play different roles, such as neighbor, authority and emergency contacts, and receive real-time notifications about risk or emergency situations in their area.

For example, if a neighbor witnesses a suspicious act or crime in your neighborhood, you can use the app to alert local authorities and other nearby neighbors as well as your emergency contacts.

In addition to notifications, the application can also provide useful information for users and authorities such as the coordinates of the emergency or risk.

In short, a community security app that launches notifications as alerts in different roles can be an effective tool to increase security and prevent crime in the community. It provides a quick and easy way to communicate risk and emergency situations to authorities and other nearby neighbors, and can be a valuable part of any community safety strategy.
