Background and Objective: Health Information Technology helps individuals prevent COVID-۱۹. Many information technology applications have been developed to prevent Coronavirus infection globally; however, the quality level of these applications is uncertain. This study aims to evaluate the usability of the Mask mobile application, which is designed to fight COVID-۱۹. Materials and Methods: The Mask mobile application is evaluated in two phases in this study. In the first phase, five experts performed the evaluation by Jacob Nielsen's ۱۰ general principles, and in the second phase, ۱۲۴ participants evaluated the Mask mobile application. Data collection tools were the System Usability Scale (SUS) questionnaire. Results: Mask mobile application was poor in experts evaluating it in terms of error prevention, flexibility, and efficiency. In the user-based test method, the user score of this application was ۸۹ out of ۱۰۰, which was equal to an excellent ranking and grade A. Conclusion: The results have indicated that the usability of the Mask mobile application to prevent COVID-۱۹ has been excellent. As a result of the study, mobile application developers might improve or modify their existing mobile health application designs to achieve optimal outcomes.
