Doctor Appointment App Development -- 2

I want a clean, intuitive mobile application that lets physicians handle patient bookings from their phones on both iOS and Android. Core flow is simple: a doctor signs in with an email-and-password account, sees their calendar, reviews a patient’s medical history, and confirms or reschedules the slot.

To make that happen, the build must include:
• Appointment scheduling with real-time availability management
• Secure access to each patient’s stored medical history (read-only for now)
• Push and in-app notifications for new bookings, reminders, and any changes

A single codebase (Flutter, React Native, or similar) is preferred so maintenance remains straightforward across the two stores, but I’m open to alternatives if you have strong reasoning. The UX has to feel native on both platforms, handle poor connectivity gracefully, and encrypt data at rest and in transit.

Deliverables I’ll review for sign-off:
1. Production-ready iOS and Android builds plus store-submission files
2. Complete, well-commented source code
3. One-page setup/run guide and brief API spec for the appointment and patient-history endpoints
4. Short demo video or live walkthrough showing login, booking, history view, and notification flow in real time

Send a quick outline of your proposed tech stack, timeline, and any similar healthcare apps you’ve shipped, and we can lock the milestones.
