Identity and hardware
Model, serial, storage, colour, memory and the battery behind a real health figure.
Desktop app for used phone shops
Grade every second hand phone with proof
PhoneGrade plugs a phone in over USB, reads everything it will tell you about itself, runs eleven interactive hardware tests in the phone's own browser, and turns the result into a grade, a label and a report you can hand a customer.

What it checks
The whole phone, not a summary
A screen grab from a diagnostics tool tells you almost nothing.
Locks and status
Activation lock and Find My from four separate sources.
Original parts
Nine components on iOS compared against factory values.
Touch and display
A 112 cell grid to find dead zones, then five full screen colours.
Audio, cameras, sensors
Every camera lens photographed on a timer, then reviewed side by side.
Crash history
iOS panic logs matched against a rule set from the repair communities.
Grade, label and report
A, B or C, the invoice method, a DYMO label and a customer facing PDF.
Labels, reports and exports
What you can hand over, print or load into your own system.
Features
The part that matters
It tells you what it does not know
A grading tool that guesses is how a shop ends up selling a bad phone.
Withheld is not the same as absent
On iOS 15 and newer the domains carrying component serials answer with an empty property list.
A refused microphone is not a dead microphone
A refused permission is recorded as a choice, not a defect.
Missing hardware means the grade goes down
A device that cannot do what it claims cannot be sold as though new.
Nothing leaves the phone
Camera and microphone streams stay on the handset.
How a phone gets through
Plug in, scan, grade, print
One window, four states.
Connect over USB
iPhone, iPad or Android, detected and read in a couple of seconds.
Scan with the phone
A QR code opens an interactive suite in the phone's own browser.
Grade and print
The report lists only what was wrong, then the label goes to the printer.
Next device
Unplug mid test and the device is remembered, so the run resumes.
