I need a standalone mobile application that runs smoothly on both Android and iOS devices and streamlines our day-to-day hospital operations. Core modules I want built: • Patient management for quick registration, detailed profiles, and visit history • Appointment scheduling with an intuitive calendar, reminders, and easy rescheduling • Billing & invoicing that can create, edit, and export invoices on the spot • Medicine order handling so the pharmacy can receive and update requests in real time • Lab order management to log tests, track status, and record results Scope of work: – Design a clean, user-friendly interface that works on phones and tablets. – Develop the full app in a modern cross-platform framework (e.g., Flutter, React Native). – Implement secure authentication and role-based access for doctors, nurses, admin staff, and cashiers. – Include concise in-app admin controls so we can manage data without a desktop dashboard. – Provide thorough testing, bug fixing, and deployment to both app stores. – Hand over well-documented source code, build instructions, and a short user guide. This project is entirely greenfield; no integration with existing hospital software is required at this stage. In your proposal, outline your chosen tech stack, similar healthcare apps you’ve delivered, and a realistic timeline from kickoff to store release.
