TAPulis

Civilian-to-Police Emergency Alert System

Winner — QPPO ICT Innovation Challenge 2026

Overview

TAPulis is a hybrid platform consisting of a web-based management system and a native mobile application. The web platform is used by administrators and superadmins for monitoring, analytics, and incident management. The native mobile app is used by civilians and responders for real-time reporting, GPS tracking, and emergency actions. The system enables tap emergency alerts, community tip submissions, and a hold-to-call 911 feature, ensuring both digital reporting and direct emergency communication.
