幸福工友 is an Android application developed by Edmond Yu, designed specifically for construction workers. This free app aims to integrate four existing systems used by China Construction Hong Kong for managing on-site personnel. These systems include facial recognition attendance, safety ratings, health declaration, and automatic registration for new employees.

The app provides a unified platform for construction workers to access these systems, offering a better user experience. Additionally, it serves as a platform for workers to access more benefits, provide feedback, and receive information updates.

In the future, the app plans to further develop features related to personnel management based on the needs of construction sites. This may include recording training records and tracking the distribution of safety equipment.

幸福工友 is a valuable tool that streamlines various systems used by construction workers, making their work more efficient and improving their overall experience on the job.
