Migrating your existing iOS and Android apps to React Native often feels like open-heart surgery: complex, risky, and disruptive. But what if adding React Native could be simple, incremental, and non-disruptive?

In this practical session, Michał Pierzchała introduces a simpler, streamlined approach to brownfield development with React Native, powered by Callstack’s [Rock](https://www.callstack.com/open-source/rock). Michał will demonstrate how you can seamlessly integrate React Native into your existing mobile apps without complicated monorepos, CocoaPods hassles, or interrupting your ongoing releases.

Watch the talk to learn:

- How Rock drastically simplifies React Native integration for iOS and Android
- Step-by-step setup to effortlessly embed React Native screens into existing apps
- Real-world strategies for incremental adoption without feature freezes or big rewrites
- Best practices for keeping your app performant, native-feeling, and well-observed
