Roll Call was created to address two core challenges in education: the inefficiencies in attendance tracking and the decline in student participation. The app utilizes a real-time, dynamic QR code system that ensures accurate and instant attendance verification for both students and professors. By seamlessly integrating a web platform with the app, Roll Call delivers a streamlined experience that not only tracks attendance but also provides students with essential university updates, event notifications, and a personalized calendar to manage their classes and campus activities.
