Device health check

Guided pre-sale inspection for a phone, tablet, laptop or watch where every result says whether the browser measured it or a person confirmed it, ending in a graded report with redacted identifiers.

How this works

You answer a short list of checks tailored to the device type. Some are measured by the browser (speaker tone, camera, motion, battery, vibration, touch) and the rest are things you look at and confirm by hand. Every result on the report says which kind it is. At the end you get a graded report as plain text you can copy for a buyer. Everything stays on this device.

The grade comes from the checks you answered: measured and confirmed passes both count, and failures on essential checks cap the letter (two failed essentials grade F). More than two essential checks left untested ends the report Incomplete instead of a grade. The serial is masked to its last four characters and the IMEI to its last four digits before the report is built, and nothing leaves this tab: there is no server share link, only text you copy. This page cannot test a touchscreen's pixels, a laptop keyboard, ports, or a watch's heart sensor; those stay person-confirmed checks, and the report says so on every row.
