HerCircle
Women's Safety Network App
A Flutter-based mobile application providing real-time location sharing, silent alerts, and circle-based monitoring for women's safety. Features geospatial intelligence and real-time subscriptions.
// the problem
Challenge
Building a safety app requires absolute reliability—lives depend on it. The technical challenges include accurate background location tracking, instant alert delivery, privacy-first design, and cross-platform consistency. Geospatial intelligence enables powerful location queries while maintaining battery efficiency.
// what we built
Solution
HerCircle uses Flutter with Supabase backend for real-time sync. The safety loop shares journeys with trusted contacts, triggers silent alerts when ETA is exceeded, and provides fake call disguise for emergency situations. Advanced geospatial processing handles location-based features.
