A survey-based methodology is used to collect data from a random sample size of 137 enrolled students in the College of Business Administration (CBA) at Prince Sattam bin Abdulaziz University. The results demonstrate the state of usability attributes of PSAU mobile application is acceptable; the highest mean was 3.3 for the cognitive load dimension, after that, the learnability and memorability dimensions with mean 3.0. The lowest mean is 2.4 for the Efficiency dimension. The overall mean for usability is 2.8 which reflect the level of usability for the PSAU mobile application. The results of this study should be useful to IT deanships and related policymakers at the university level with empirical evidence about the issues and problems that faced users of mobile applications in higher educational institutions in KSA; and helping in developing high-quality mobile application.
