Why CheckAmm
Whether you're buying, selling, or repairing — know exactly what you're dealing with.
Test camera, speaker, mic, touch, sensors & more directly in your browser. No app needed.
Get a risk score based on reports, ownership history, and community data. Know the risk before you buy.
Get a complete picture — hardware condition + ownership history — before any transaction.
How It Works
On a phone? Enter the IMEI first. On a laptop? Jump straight to tests.
Tap 'Run All' or test individually. Camera, speaker, mic, touch, sensors — all checked in your browser.
See what passed and what failed. Export a diagnostic report or share the results.
CheckAmm App
CheckAmm app users can attach a hardware report to any registered device — so buyers see a verified hardware grade alongside the full ownership history.
Test the device on CheckAmm, then tap Generate Share Link. You'll get a permanent report URL.
Your link looks like checkamm.com/r/ABC123. The report ID is the short code at the end — copy just that part.
Open the device in the CheckAmm app → tap Link Hardware Test → paste the report ID. Your listing now shows a verified hardware grade.
Why does it matter?
A linked report shows buyers exactly what passed and what failed — it's not the seller's word, it's a timestamped test result they can verify themselves at checkamm.com.
