Expo Observe dashboard

Edit page

View performance metrics, filter by platform or version, and investigate individual sessions in the Expo Observe dashboard.

The Observe dashboard provides a visual overview of your app's performance metrics. Open your project and in EAS dashboard, select Observe from the navigation menu.

Statistical breakdowns

For each metric, the dashboard displays:

Median: The middle value, representing typical user experience
Average: The arithmetic mean across all events
Min/Max: The fastest and slowest recorded values
Percentiles (P90, P99): Values below which 90% or 99% of events fall, useful for identifying tail latency

Time range selection

View data from the last 1 hour, 12 hours, 1 day, 3 days, 7 days, 30 days, or 60 days.

Release comparison

The dashboard shows how metrics have changed between releases (for example, "+0.2s since last release"). Release markers on the chart indicate when new versions were deployed.

Hover over a release marker to see an overlay of metrics for that version. Click the marker to view all events for that release.

Filtering

You can filter metrics by:

Platform: Android or iOS
App version: Filter by native app version
Update version: Filter by OTA update version
User: View all events from a specific user
Session: View all events from a specific session

Investigating sessions

When something looks off in your metrics, drill into individual sessions to see:

All events recorded during that session
Device information (model, OS version)
Session metadata

This helps you understand why certain users experience slower performance, whether it's a specific device, OS version, or network condition.
