What is EAS Observe
EAS Observe is a performance monitoring tool built for Expo and React Native. It measures app startup time and per-screen time-to-usable on real user devices, and reports metrics through the Expo dashboard. Sessions include device context such as model, OS, country, network type, thermal state, and frame data, and each native build and EAS Update is marked on charts so teams can see which release affected performance.
Key Features
Use Cases
- Monitoring startup time of Expo and React Native apps in production
- Identifying which app release or EAS Update impacted performance
- Diagnosing slow screens using device, OS, and network context
- Tracking performance regressions across devices, regions, and network conditions
Why do startups need this tool?
Startups building Expo and React Native apps can add production performance monitoring with minimal setup, see how each release affects startup and screen performance, and start on a free plan without upfront cost.
