Expo Observe is a new product developed by Expo that helps you measure app performance and identify bottlenecks in your app. It gives you insight into how your app behaves in real-world conditions and helps you understand where performance issues come from.

In this talk, I will show how to use Expo Observe to find and fix performance problems in production apps. You will learn how to spot common issues, understand performance data, and use it to make your app faster and more reliable.

Whether you're trying to understand if a recent release improved performance, track down a bottleneck affecting a subset of users, or simply gain more confidence in the quality of your app, you'll leave with a better understanding of how to use performance data to build faster and more reliable applications.

The React Native ecosystem is more than just a framework. It is the people building the libraries, the tooling, and the invisible infrastructure that make modern mobile apps possible. This panel looks at the projects developers rely on every day, the challenges of keeping them maintained and evolving, and the community effort required to keep React Native moving forward. We’ll discuss what’s changing in the ecosystem, which tools are becoming essential, how maintainers decide where to invest their time, and what developers should know to build with confidence today and beyond.
