iOS & Android App Development

I need a full-cycle mobile application built for both iOS and Android. The project covers everything from setting up the codebase and designing an intuitive UI through to backend integration, testing, and final deployment to the App Store and Google Play.

Please work in a modern cross-platform stack—React Native, Flutter, or a similar framework—so that most of the codebase is shared while still giving each platform a native feel. If you prefer separate Swift/Kotlin builds, I’m open to hearing why that would be a better fit once you understand the feature set.

Key deliverables I will be looking for:
• Complete, well-structured source code stored in a Git repository
• Pixel-perfect UI that matches provided wireframes (or created collaboratively if wireframes are absent)
• Secure, documented API integration and local data persistence
• Automated tests covering critical user flows
• Release-ready builds plus guidance through App Store and Google Play submission
• A brief hand-off document so future updates remain straightforward

The functional specification and wireframes will be shared after we sign an NDA. For now, assume the app will require user authentication, real-time data syncing, and push notifications. My timeline is flexible enough for thorough quality assurance but tight enough to keep momentum, so clear milestones and regular progress demos are essential.
