With the abundance of mobile apps available, users are becoming increasingly sensitive to app quality as a differentiator when deciding which app to use. To counter this, mobile app developers need to address quality concerns with bug reporting and crash reporting tools, but also implement mobile application performance monitoring (APM) to stay on top of their app's performance and improve it to deliver the best experience for users. APM helps track key app performance indicators, including metrics like app launch and loading times, screen and content loading times, and other aspects of an app's performance. By using APM tools, developers can monitor the end-user experience, application discovery, tracing, and diagnostics, as well as application analytics to identify areas for improvement. This proactive approach allows developers to discover and fix performance issues before they become one-star reviews and lost revenue. Key components of APM include end-user experience monitoring, application discovery, tracing, and diagnostics, as well as application analytics. By using a mobile app performance monitoring tool like Instabug, developers can track key metrics, such as Apdex scores, UI hangs, network timeouts and issues, slow launches, custom traces, and more, to improve their app's performance and deliver the fastest and most reliable experience for users.
