Staying informed about crime and safety in a bustling city like Brooklyn is crucial. The Citizen app offers a unique solution by providing real-time alerts and incident reports. But how does it work?

Real-Time Crime and Safety Alerts

Citizen aggregates data from multiple sources, including official police reports, fire department dispatches, and user-submitted reports. This creates a comprehensive picture of incidents happening around you.

Location-Based Notifications

The app utilizes GPS to deliver alerts specific to your location in Brooklyn. This means you'll only receive relevant information affecting your immediate area.

Crowdsourced Information

Citizen employs a crowdsourcing model, allowing users to submit their own reports and videos. This community-driven approach ensures timely updates and comprehensive coverage of events.

Visual Mapping of Incidents

The app features an interactive map displaying the locations of various incidents. This allows you to visualize the safety landscape around you.

Importance of Verification

While Citizen is a valuable tool, remember that information is often preliminary. Always cross-reference with official law enforcement sources for confirmation.

Conclusion

The Citizen app serves as a helpful tool for Brooklyn residents to stay informed about safety and crime in their neighborhood. It is a supplementary resource for keeping informed, not the sole source of information.
