EAS Observe vs Embrace User Session Insights

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.

Embrace User Session Insights helps teams investigate mobile app issues by recreating user journeys with production data. Session timelines combine technical and behavioral details, including vitals, webviews, taps, network calls, crashes, and push notifications. Teams can search and filter event details in the User Timeline, which shows session duration and a technical summary, and segment sessions by device, location, OS version, or app version. For issues, errors, and crashes, user impact analysis provides a view across the user base. The product page describes sessions as unsampled and user data as compliant and anonymized. It runs in the cloud and supports Android, iOS, and web, with frontend monitoring, release tracking, source-map support, and session replay. Free includes up to 1 million sessions per year, up to five users, and three days of event data retention; ingestion stops when either cap is reached unless the customer upgrades. Pro costs 0.80 USD per 1,000 sessions with an 80 USD monthly minimum, and includes up to 10 users and 14 days of retention. A 30-day Pro trial is available. Enterprise has custom pricing and 30 days of retention.
