However, providing sustainable professional development programs is difficult because of various challenges, such as a scarcity of qualified personnel and Lack of training opportunities, lack of access and resources, etc. For teachers’ professional development, educational institutions currently favor adopting and using modern educational technologies. As a result, various mobile apps have been developed and implemented in educational institutions in recent years. This paper presents the findings of a study that looked at the Usability of our designed mobile App for teachers training in Sindh by employing one of the most widely used usability criteria, SUS. It also investigates the relationship between these variables and the impact of teachers’ demographic characteristics on the SUS Score. The study’s findings achieved a 100% completion rate for all tasks, indicating an extremely effective, efficient, and sustainable system. Moreover, the satisfaction percentage was also found to be 84.1 percent, considered highly satisfactory.
