Obtaining accuracy and robustness is a very challenging task in a geolocation-based mobile application. Many geolocation-based mobile applications lack the ability to achieve high accuracy and do not incorporate essential features like SOS functionality. Accuracy plays a critical role in geolocation mobile applications, as they must send exact locations to emergency agencies to ensure prompt and effective assistance. Similarly, robustness is crucial, as the application should function reliably under all conditions. This present study on the development of a geolocation-based mobile application integrates all these new features while achieving high accuracy and robustness. Many geolocation-based mobile applications have features distributed across separate apps; however, this geolocation-based mobile application consolidates them into one single app. The developed application not only integrates police, ambulance, and fire engine services but also offers continuous location tracking, one-click emergency calls, and the ability to identify nearby hospitals, police stations, and fire departments. This comprehensive approach significantly enhances the efficiency and effectiveness of emergency response, providing users with a reliable and user-friendly tool during critical situations.
