Users are struggling with the sheer number of apps available, making it challenging for mobile teams to get users to download and stay on their apps. App health refers to an app's stability, UI/UX issues, and other metrics that can be quantified and optimized. To monitor app health, developers need to track metrics such as bugs, performance, and crashes. Effective tools, like APM (application performance monitoring) tools, can help identify bottlenecks and allocate resources to maintain a healthy app. By tracking stability scores, crash reports, and other metrics, mobile teams can catch issues before they affect users and improve their app's overall health.
