Cross-Platform Telehealth App Development

I’m ready to kick off a new telehealth app that runs smoothly on both iOS and Android. The core goal is to let patients and clinicians connect through secure video consultations and in-app messaging, backed by HIPAA-compliant data handling.

Scope
• Design: Wireframes, polished UI mock-ups, and a clear user flow for patients and providers.
• Build: Native or cross-platform codebase that launches on the App Store and Google Play, including secure sign-up/login, profile management, real-time video, and push notifications.
• Admin: Simple web or in-app dashboard so I can manage users, appointments, and session history.
• Testing: Functional, usability, and device-coverage tests, plus hand-off of source code and build instructions.

I’d like a clear milestone plan outlining design, development, internal testing, and store submission. If you have experience with Swift/SwiftUI, Kotlin, Flutter, or React Native plus third-party video SDKs (e.g., Twilio, Agora), let me know which stack you recommend and why.

Send a brief overview of similar healthcare apps you’ve shipped, your suggested tech stack, and timeline so we can move forward quickly.
