In a competitive mobile app market, ensuring continuous availability and a seamless user experience is crucial to minimize user churn. Mobile apps face unique challenges due to the variety of devices and the time-consuming nature of rolling out updates, unlike web apps. Key performance metrics such as app start time, view rendering time, network performance, and resource utilization are vital for monitoring app health. Understanding user actions and collecting crash data are essential for diagnosing errors and enhancing user experience. Tracking these metrics helps developers identify performance issues and prioritize optimizations. Datadog offers tools for mobile real user monitoring, end-to-end tracing, and error tracking to help developers maintain high app performance and availability.
