EAS Observe
EAS Observe is a production performance monitoring service for apps running on real devices and conditions. It records cold and warm launch times, time to first render, time to interactive, bundle load time, and EAS Update download time. Measurements can be compared across app versions and over-the-air updates to help identify regressions. Expo Router and React Navigation integrations add render and interactive timings for individual routes. Apps can send user-defined events with Observe.logEvent and analyze them with performance data. Results appear in the EAS dashboard or can be queried from the terminal with EAS CLI commands. EAS Observe supports Android, iOS, and tvOS, but requires Expo SDK 55 or later and an app linked to an EAS project. It is unavailable in Expo Go and needs a development or production build. JavaScript error and native crash reporting are preview features. Plans include Free at $0/month, Starter at $19/month plus additional usage, and Production at $199/month plus additional usage; Enterprise pricing is custom. Retention is 90 days.
