This paper presents the development of Rescuennect, a mobile application designed to enhance roadside assistance and emergency response services on Siargao Island using telematics technology. The application integrates GPS and Google Maps API to provide real time tracking, service availability, and a directory of roadside assistance and emergency response services. Users can request services such as battery jumps, flat tire changes, gasoline delivery, and towing with a few taps while tracking response times and the progress of assistance personnel in real time. Additionally, Rescuennect updates traffic conditions, road closures, and nearby points of interest. Developed using the Rapid Application Development (RAD) model and evaluated using ISO 9126 standards, Rescuennect achieved high scores in usability (4.37), functionality (4.13), and maintainability (4.20). This integrated approach promises to revolutionize Siargao Island's roadside assistance and emergency response landscape, providing faster, more reliable, and transparent services for residents and tourists.
