# Expo
Supported OS Integration version1.0.0
## Overview{% #overview %}

With the Datadog [Expo integration](https://app.datadoghq.com/integrations/rum-expo), you can spend less time triaging issues and more time releasing new features by:

- Debugging the root cause of slow performance issues and application crashes in third-party libraries, network requests, or large media files
- Improving application responsiveness, setting up service level indicators (SLIs), and diagnosing issues with out-of-the-box dashboards, real-time metrics, and deobfuscated crash reports
- Intelligently grouping high-volume application errors into a manageable set of unique issues

Correlate the impact of the user experience on your business by:

- Analyzing critical mobile user experience data such as screen engagement by demographics, version releases, or any custom attributes, to reach your business KPIs
- Automatically correlating every user journey with a timeline of session events and attributes including ID, cellular activity, referral URL, and more
- Understanding user behavior trends with customizable analytics and geographical maps

Monitor the end-to-end health of your Expo application by:

- Pivoting from your user experience data to backend traces, runtime metrics, and logs for the complete context when investigating issues
- Debugging crashes faster by unifying client-side and server-side metrics, traces, and logs
- Unifying full-stack monitoring in a single platform for frontend and backend teams
