The main objective of this study was to develop a web-based, mobile-responsive information management system for the health centers in the province of Negros Occidental (Western Visayas, Philippines). For this purpose, the constructive research approach was used, including data collection methods such as face-to-face interviews, observation of the current workflow, and analysis of the existing records, forms, and other relevant references. Rapid Application Development (RAD) guided the development process. The system is focused on providing an information management system including the following features: record management, report generation, SMS notification, and user account management. After the development, the system was assessed by three experts. The results showed that the system allowed the subject health centers to have a prenatal check-up record management, report generation module, personal prenatal journals, and a check-up schedule reminder. The overall score of the evaluation was 2.55, which implies that the system performs acceptably under the eight factors used to evaluate the system performance.
