MetricKit watches how your app runs on real Apple devices. It collects performance numbers like CPU usage, memory, and launch time. It also gathers crash reports and other errors.
You get a daily report with all this data. This helps you find problems and make your app faster. You can also see details like call stacks for crashes.
Setting it up is simple. You just add a subscriber to your app. MetricKit does the rest automatically.
