Emergency Ghana - Citizen Mobile Application
An offline-first, safety-critical mobile application designed to connect Ghanaian citizens with emergency response services (Police, Fire, Ambulance, Road Safety) instantly. Currently in Closed Testing on the Google Play Store, the app resolves user coordinates locally and syncs with the national directory, enabling one-tap emergency calling and guardian escalations even in zero-connectivity environments.
