Cross-Platform App with Notifications

@CANWS

Hi, I can update your existing mobile app to include production-ready user authentication (email, social, or phone) and fully functional push notifications triggered manually via an admin console or automatically from server events. The updated build will run from a single codebase on both iOS and Android, with a minimal placeholder home screen to demonstrate flows. ✅Deliverables: Updated source code with clear structure Compiled APK and IPA (TestFlight) README detailing build steps, notification setup, and third-party services I can recommend the optimal stack (Flutter ) for maintainability and fast future updates, and I’ve shipped similar apps with secure login and notification features.

I’ve reviewed your requirements and understand this is an update to an already published app, focused on delivering a single code-base iOS + Android build with rock-solid authentication and push notifications. I can update your existing app using a maintainable cross-platform stack (Flutter or React Native), implement a production-ready auth flow (email/social/phone as appropriate), and set up reliable push notifications that can be triggered both from an admin console and server events. The result will be a clean, minimal release that clearly demonstrates login and notification flows, delivered with full source code, updated builds (APK + TestFlight), and a clear README covering setup, build steps, and notification configuration so future updates stay straightforward.

I have hands-on experience working with React Native and Flutter, and I will recommend the best stack based on long-term maintainability and performance. For authentication, I will implement a production-ready and secure login system (email/phone/social as suitable), and integrate reliable push notifications using Firebase.
