A key metric in your mobile application's health is app start time. We've introduced a new view, called App Starts, that leverages the automatic instrumentation in the Android and iOS SDKs to highlight specific changes in your app start spans between releases. You can now easily monitor your app start performance, and drill-down into a screen's start up time all the way down to events and profiles for span operations causing slowdowns.
