This identifier is exclusive to each app installed on your iPhone. It identifies an application that has been installed on the respective device.

Moreover, it will continue to do so until you uninstall the application from your iPhone. Assume that a user gets rid of the application from their iPhone and then redownloads it. Then, the UUID becomes different than it was before.

Basically, your device has something called a UDID, which is its own unique identifier. And each app has something called a UUID, which is its own unique identifier until it remains installed.
