MyITS Mobile is often used by various academic parties such as students, lecturers, and teaching staff, as well as student trustees. In addition, system is run in several operating systems and software that have different characteristics. Therefore, it is necessary to guarantee maximum quality of portability of system. Portability quality assurance is measured by ISO/IEC 25010 quality standards with sub characteristics namely characteristics, namely Adaptability, Installability, Replaceability. This study aims to measure quality of portability on MyITS Mobile using ISO/IEC 25010 quality standards. By measuring the quality of portability using six metrics on three sub characteristics obtained a maximum calculation result of 1.0. It proves that the MyITS application can run well in a variety of environments, especially on the Android and IOS operating systems. However, although some features needed by each user have been running well, there are some features that have not been completed in the process. As a result, some features do not function and run properly in accordance with the design of MyITS mobile.
