A few things to know.
Answers before you download.
What can I check on my iPhone?
The app includes checks for display and touch, cameras, audio, sensors, Wi-Fi, Bluetooth and system functions. Available checks depend on your device and permissions.
Are all checks automatic?
Quick Test gives you a starting point. Professional tests include manual verification, so some checks ask you to interact with the phone or confirm what you see or hear.
Is it useful before buying a used iPhone?
You can use it as a functional checklist before purchase and review a test report. It does not guarantee device condition, authenticity or remaining lifespan.
