Cross-Platform Mobile App Development

I’m looking to build a cross-platform mobile application that works smoothly on both iOS and Android. The core idea is defined, but the exact feature set is still flexible, and I’d like guidance on finalising the scope and choosing the most suitable technology (Flutter, React Native, or native development) based on performance, cost, and long-term maintainability.

The project will involve full end-to-end development, including clean and well-documented code, a modern and intuitive UI/UX, and secure user authentication. The app may include features such as push notifications, in-app purchases, and basic backend integration, which we can finalise together during the planning phase.

I will provide wireframes, branding assets, and a high-level product vision once the project starts. The final deliverables should include testable builds for both platforms and support with deployment to the App Store and Google Play. I’m looking for a reliable freelancer who can suggest best practices, communicate clearly, and help turn this idea into a polished, production-ready mobile application.
