Taskeen — Hajj Pilgrim Tracking & Management App

Overview

Taskeen was developed to help Hajj organizers manage and monitor pilgrims throughout their journey. Each pilgrim wears a bracelet with a unique QR code linked to their profile. Scanning it via the Taskeen app instantly reveals details like assigned group, contact data, and location — enabling faster, safer, and more efficient coordination during Hajj.
