Breadcrumbs can be incredibly useful for mobile app developers to gather specific information at designated points in their app, build a story around poor performance, and understand user flow through an app. By adding breadcrumbs to key workflows, such as login processes or shopping cart flows, developers can make troubleshooting much easier after their app is released. This can help identify issues like frequent token refreshes, improve app store reviews, and decrease support tickets. With the use of mobile breadcrumb custom events in New Relic, developers can correlate information between session data and breadcrumbs to build performance stories and gain insights into user behavior.
