Student-Teacher Connect Mobile App -- 2

I need a production-ready mobile application that lets students find, book, and interact with teachers on both Android and iOS from day one in the stores. At its heart the app is a real-time bridge: learners browse teacher profiles, pick a slot, and immediately call from phone or open a chat to ask questions.

Core interactions I must see working smoothly:
• In-app chat messaging that supports text, images, and quick voice notes.
• One-tap audio/video calling once a booking is confirmed.

Around those pillars, the experience should feel complete:
• Scheduling & booking with calendar sync and push reminders for both sides.
• Rating & reviews after every completed lesson so quality stays visible.
• Lesson sharing & storage—recordings, notes, or files should land in a personal library the student can revisit any time.

Give me a clean, modern UI, full profile management (bio, subjects, pricing, availability), and a small admin web panel so I can manage users, classes, disputes, and payouts without diving into code.

Tech stack is up to you—Flutter, React Native, or true native builds are all fine as long as:
• One code base serves Android & iOS with identical feature parity.
• The backend is documented (Firebase, AWS, Node, etc.) and deployable with one command.
• GDPR-ready authentication and secure payment integration are in place.

Hand-off package:
1. Source code with clear comments.
2. Running builds uploaded to TestFlight & Google Play Console (internal track).
3. Database schema and deployment steps.
4. A short video walk-through proving every feature above works.

If anything on this list looks unclear, flag it early so we can lock scope before you start coding.
