The paper designs and implements an innovative global positioning system (GPS)-based mobile application to pinpoint the location of an individual in case of an emergency and easily notify emergency contacts or response centers in real-time. This improves response time and enhances overall safety of lives and properties. The methodology used for the system is object-oriented design (OOD) model, in which system components are treated as objects that interact with each other. The tool and programming language used for the development are Google Maps for display of precise location information and Flutter/Dart programming language for development of multi-platform applications using a single code base. The app will help those in danger obtain timely intervention and assistance from trusted individuals or organizations, thus saving lives and minimizing potential harm in emergency situations.
In Nigeria and many other countries of the world today, the threat posed by terrorism, kidnapping for ransom, violent crime, civil unrest, piracy, vandalism and banditry (armed robbery) tend to exacerbate humanitarian crisis, safety of lives, political instability and financial risks (Security Council Report, 2025). The rising need to protect human lives and properties in the event of a crisis is, therefore, evident and persuasive across the globe. With the rapid expansion of cutting-edge technologies, mobile phone operating systems are now integrated with sophisticated features like WiFi, global positioning system (GPS) chip, Internet of Things (IoT)-enabled devices, artificial intelligence (AI)- powered algorithms, high resolution camera and touch screen to help mobile users interact with the outside world.
