It takes more than a similar codebase to develop a mobile application that runs on both iOS and Android. Even though React Native enables developers to share JavaScript or TypeScript code across platforms, every operating system has interface conventions, permission systems, hardware capabilities, and performance characteristics. Disregarding such differences may result in inconsistent user experiences, unforeseen errors, and extra maintenance expenses.

An effective cross-platform application will strike a balance between reuse of code and platform needs. React Native Development Companies solve these issues by finding the differences between operating systems early, structuring code, and testing applications on both platforms during the development process.
