The us. of thes. apps.eas.s.our daily lives. and all cus.omers.who need any type of s.rvice can acces.it eas.ly, comfortably, and efficiently through mobile apps. Particularly, s.udi Arabia greatly depends.on digitals.rvices.to as.is. people and vis.tors. s.ch mobile devices.are us.d in organizing daily work s.hedules.and s.rvices.particularly during two large occas.ons. Umrah and Hajj. However, pilgrims.encounter mobile app is.ues.s.ch as.lownes., conflict, unreliability, or us.r-unfriendlines..
