Instabug's React Native APM tool helps developers track key metrics to improve their app's performance, including Apdex scores, UI hangs, network timeouts and issues, slow launches, custom traces, and more. This update also brings push notifications to the React Native SDK. The App Apdex score provides a single numerical representation of an app's overall user experience, and Instabug's tool helps align teams around one KPI and communicate it to all stakeholders. UI hangs are assessed by comparing delay in responding to user input to total time spent on a screen, while network performance is tracked from the users' standpoint. Execution traces measure client-side logic completion time, and app launches show how long users wait until the app loads and is responsive. Instabug's tool empowers mobile teams to maintain industry-leading apps with stability and performance monitoring, combining APM, Crash Reporting, and Bug Reporting for a complete picture of an app's quality, performance, and stability.
