This study tests and measures the usability of mudah.my mobile application in terms of its efficiency, effectiveness, and satisfaction. Ten participants conscripted for the study performed five tasks on the application’s interface. A summative usability evaluation based on user performance and perception was carried out. The usability testing was conducted at Universiti Utara Malaysia (UUM) and the results obtained show that the Mudah.my mobile application is easy to use and consistent as seen from the analysis and observations made. However, the app is laden with some usability issues that should necessitate improvement. The study’s outcome will benefit developers and usability engineers in providing a user-friendly and usable application that meets users’ needs.
