About this app
Auditor helps you verify that your Android device is genuine and hasn't been hacked or tampered with. It uses hardware-backed security checks built into your phone to confirm that the operating system hasn't been secretly modified.
You can pair it with a second device to check your phone via a QR code, or set up scheduled remote checks that alert you by email if something looks wrong. It's a strong extra layer of protection for anyone who wants real peace of mind about their phone's integrity.
