## AI overview

This guest post explains how the Usage system activity monitor uses Sentry to detect crashes, silent errors, build issues, and user feedback problems. The app runs across iPhone, iPad, and Mac and depends partly on undocumented APIs, so OS updates can change data structures without notice. Separate Sentry projects track the app's cooperating components and their failure modes.
