This study sought to attain the following objectives: (1) to determine the requirements of E-Appointment in terms of: (a) data, process, output (h) software architecture (c) hardware and software requirements; (2) to design and construct the E-Appointment.; (3) to determine the level of usability of the E-Appointment. The researchers used descriptive and developmental research methods. The researchers utilized the Application Development Life Cycle (MADLC) model. The researchers used frequency count, mean and Likert scale as statistical tools to analyze the data gathered The researchers were able to arrive to the following conclusions: the requirements of the system are very important to the development of the mobile application, the mobile application is an effective online appointment system as evidence with 4. 79 mean, and the developed E-appointment is very much usable.en-USThesis
