iCheckup: Used Phone Test

Evaluate a used iPhone or iPad with public APIs and a clear local report.

iCheckup helps you evaluate a used iPhone or iPad before buying or selling.

The app guides you through checks for device details, display, cameras, audio, sensors, battery, connectivity, and ownership status. iCheckup uses only public iOS and iPadOS APIs, and it clearly explains what can be assessed automatically and what is not available to third-party apps.

Reports stay on the device unless you choose to share them. iCheckup is not an Apple assessment, does not determine the origin of Apple parts, and does not access non-public Apple diagnostic information.
