I need a reliable implementation of app deeplinks that work seamlessly on both iOS and Android. The goal is simple: when a user taps a URL, it should open the specific screen inside our mobile app, and if the app is not installed, gracefully fall back to the responsive web page. Scope of work: • Configure Universal Links for iOS and App Links for Android. • Map key URL patterns to the corresponding in-app screens. • Ensure web, test, and production environments each have their own valid association files. • Provide a short README outlining how to add or modify routes in the future. • Supply a quick demo or video walkthrough proving the links open correctly on the two platforms. Our backend already hosts the necessary JSON files; you will just need to update and verify them. I’m happy to share the current codebase and coordinate a quick test flight build so you can validate your work on real devices. If you have previous experience shipping working deeplinks in React Native, Flutter, or native stacks, let me know—any of those will suit us as long as the final links behave consistently.
