Datadog has released Mobile Real User Monitoring (RUM) to help mobile developers improve the performance of their applications and troubleshoot errors and crashes. By connecting client-side and server-side metrics, traces, and logs, Mobile RUM provides full visibility into the performance of mobile applications. The tool allows users to monitor key performance metrics in real-time, investigate individual user sessions, set up alerts for crashes and errors, and collect analytics on user behavior. This helps developers deliver a seamless user experience and make better decisions around performance and design optimizations.
