## What is IDFA Viewer+?

IDFA Viewer is a free app that allows you to easily check, copy, and share your device’s advertising identifier (IDFA) on iOS. Request tracking authorization within the app, and once granted, you can display, copy to clipboard, and share your IDFA with a single tap. This app is ideal for those who need the IDFA for ad measurement, debugging, or marketing purposes.

【Main Features】
