A comprehensive safety and crime awareness application with geolocation tracking and intelligent alert notifications.

SafeSense.World is designed to provide users with real-time safety information and crime rate awareness based on their location. The application uses geofencing technology to detect significant changes in crime rates and provide timely notifications to keep users informed about their surroundings.

• Geolocation Tracking: 5-minute interval location tracking
• Crime Rate Analysis: County-level crime rate data integration
• Geofence Alerts: Notifications when crime rates change by >5% upon crossing geofences
• Firebase Backend: Real-time data synchronization and user management
• Push Notifications: Consistent alert delivery system
• Emergency Alert Integration: County-level emergency notifications
