City Diagnostic Center – A Mobile App for Digital Healthcare Management

Healthcare is undergoing fast digital change, with mobile applications playing an important role in improving service delivery and patient engagement. This paper introduces the City Diagnostic Center App, a mobile solution for optimizing diagnostic operations such test bookings, appointment scheduling, report uploads, and patient-doctor communication. Built using Android Studio and Java and powered by Firebase Realtime Database and MySQL, the application provides real-time updates, safe login with Firebase Authentication, and push notifications for smooth communication. The program improves the workflow for diagnostic center managers while also providing a comfortable platform for patients to manage their health tests. The app enables patients to browse tests, submit prescriptions, request home sample collection, receive digital results, and manage their medical history. Staff-side features include appointment management, report posting, and patient communication. Data security and encryption mechanisms have been implemented into Firebase services to assure patient privacy and compliance. Pilot testing with 25 users revealed a 70% increase in operational efficiency and 60% improved customer satisfaction. The document describes the project’s development lifecycle, from requirement collecting to system design, implementation, testing, and deployment. Additionally, it emphasizes how the suggested software fills the need in conventional diagnostic services by offering a quick, easy-to-use, and safe mobile experience. This study adds value to the current attempts to digitize healthcare services by presenting a scalable strategy for diagnostic facilities in urban India. It provides insights on technology that comparable apps might use to minimize administrative load, save costs, and improve patient happiness by using a mobile-first strategy.
