Sagip Manileño: A mobile emergency response system with SMS-based offline alert capability

Emergency response operations in Manila continue to face significant challenges due to fragmented inter-agency communication, dependence on internet connectivity, and delays in responder coordination. These limitations reduce the effectiveness of emergency management systems, particularly during disasters where communication infrastructure becomes unstable or unavailable. To address these issues, this study developed Sagip Manileño: A Mobile Emergency Response System with SMS-Based Offline Alert Capability, a mobile-based emergency platform designed to support reliable incident reporting, real-time coordination, and offline emergency communication. The study utilized a developmental research design following the Agile Software Development Life Cycle (SDLC) methodology for iterative planning, design, implementation, testing, and refinement. The system integrated Android-based mobile applications, a web-based Emergency Response Unit (ERU) dashboard, centralized database management, GPS-based tracking, real-time notifications, and SMS transmission for offline emergency communication. Results showed that the developed system obtained an overall mean score of 4.62, interpreted as “Excellent,” based on ISO/IEC 25010 evaluation involving 20 respondents. Functional testing also confirmed the successful implementation of emergency alert transmission, offline SMS capability, GPS tracking, and smart route navigation features. The findings indicate that the developed system has the potential to improve communication reliability, response efficiency, and emergency coordination under varying network conditions.
