In Hajj and Umrah, a large number of people are gathered every year to perform this ritual. Therefore, maintaining and organizing these rituals are a significant job to prevent crowding. In this paper a spatial crowdsourcing web-based application is developed to prevent crowds during hajj and Umrah ritual being performed by pilgrims specially during COVID 19 pandemic and to facilitate the movement of pilgrims. The application will monitor the pilgrim's movements by obtaining the location of the users and sorting the data within the boundaries in a map.
