In the study, the agile SDLC model was used. This will be used as a guide for the researchers to clearly define each phase and provide a well-organized system flow. Furthermore, the system was built with a variety of technologies, including PHP, HTML, JavaScript, CSS, Cron Jobs and Media Query, to facilitate understanding of the system's development process from start to finish. The aim of this study is to help the students at the Pampanga State Agricultural University. The system can help the students by providing guidance and knowledge in terms of how they can overcome excessive gaming so that they can manage their daily activities properly.
