One of the operational activities undertaken is the paper based medical record including human or animal patient. A conventional medical record has some drawbacks. Therefore, a mobile device application is required to help record medical data in unlimited space and time. It can improve the capabilities of the system and can be accessed anywhere. This paper presents the prototype of Android based medical record system at the Animal Hospital 'X'. The research produced an Android-based medical record application and REST API used for data exchange between MySQL database and, system architecture. Tests resulted that the functions in the application were working as expected while for System Usability Scaling (SUS) test got the value of 74.17. It indicated that the application was feasible to be implemented in Hospital 'X'.
