FollowMe: Tracking & Following App for Android Users

FollowMe is a GPS-based app that allows users to track and follow each other. The app encourages social interaction and uses Google Maps for visualization. With continuous GPS updates, users can securely follow friends and family. The app is designed for cheap smartphones and aims to improve location-based services. The architecture includes a web service for location updates and authentication. Currently, the app is focusing on integrating Android and web service functionalities. Future plans include adding traffic information and social networking features, as well as expanding to other mobile platforms.
