# reportApplicationIdentifier

A pseudonymn for a real application identifier.

```
var reportApplicationIdentifier: String { get }
```

## Discussion

The value of this property uniquely refers to a single app throughout the report without revealing the app’s true identity. For user privacy, the system assigns this property a pseudonymous string in cases where the [`bundleIdentifier`](/documentation/SensorKit/SRDeviceUsageReport/ApplicationUsage/bundleIdentifier) is `nil`.
