GolfGlow is a mobile application designed to help golfers manage tournaments, track player rankings, and log personal growth through an accessible, offline-first platform [1]. Developed using Flutter and relying on local storage via SharedPreferences, the app eliminates the need for internet connectivity while maintaining a user-friendly interface [2]. It features three core systems: a tournament management system for scheduling events, a ranking system for recording and updating player scores, and a profile management system for storing basic user information [3]. To evaluate its effectiveness, a survey-based experiment involving five users was conducted, yielding an overall satisfaction score of 4.12 out of 5. The results highlighted strong usability, particularly in event creation and ease of navigation, while also identifying app responsiveness as an area for improvement. Compared to existing web-based or hardware-dependent golf tools, GolfGlow offers a lightweight and inclusive solution ideal for amateur players. Its offline capability and simplicity make it a practical alternative for self-guided golf engagement and progress tracking.
