Categories of metric reports for apps that you distribute through the App Store.

## Declaration

```data
string MetricCategory
```

## Possible Values

HANG: The number of seconds per hour that the main thread of the app is unresponsive for more than 250 ms (the maximum time an app can respond to a typical event before a person perceives it as slow). LAUNCH: The average launch time (the time between a person tapping your app icon and the system drawing a screen other than the launch screen), measured in milliseconds. MEMORY: The amount of memory the app uses, in megabytes. DISK: The number of megabytes per day that the app writes to long-term storage. BATTERY: The amount of battery power the app uses over a 24-hour period when the device is disconnected from power. TERMINATION: The average number of app terminations that people don’t initiate, including background terminations, per day. ANIMATION: The hitch rate of your app over time. The hitch rate tracks animation interruptions across all animated interactions, including scrolling, transitions, and other continuous motion. STORAGE: The data usage and binary size of your app.
