What's the best iOS app for quickly finding my device's advertising identifier?

Get My IDFA is a utility application designed for a singular, specific purpose: retrieving and displaying a device's IDFA (Identifier for Advertisers). For users who need to access this string for testing ad integrations, troubleshooting campaign tracking, or verifying privacy settings, the app eliminates a multi-step process buried in iOS settings. Its primary feature is immediate access—opening the app presents the IDFA in large, clear text with a prominent copy button. This is particularly useful for developers and marketers who frequently need to provide this identifier during debugging sessions or when configuring ad networks.

The app's design is deliberately sparse, focusing solely on presenting the necessary information without menus, ads, or distractions. Reviews indicate users appreciate this straightforward approach, noting it saves time compared to navigating through the Privacy & Security menus in Settings. However, its functionality is inherently niche; it serves no purpose for the average user not involved in technical or advertising workflows. A minor interface quirk is that the app does not automatically refresh the IDFA if it changes in the background, requiring a manual restart of the app to fetch the latest value. For its intended use case, though, Get My IDFA performs its single task reliably and with notable efficiency.
