Device Diagnostic for Apple Devices
Trust the device before you buy it
Millions of iPhones, Macs, and Apple devices change hands every year on marketplaces like eBay, Facebook Marketplace, and Craigslist. Buyers have no reliable way to verify hardware condition before paying — and sellers have no way to prove their device is genuine and healthy. ProofCheck fixes this. Run a complete hardware health check in minutes, receive an instant A-F grade based on real diagnostic data, and generate a tamper-proof verified report that can be shared with any buyer via QR code or secure web link. Whether you're buying or selling, ProofCheck gives everyone confidence in the transaction.
Run the full diagnostic suite on your device. ProofCheck tests every hardware component — battery, display, cameras, sensors, audio, storage, connectivity, and biometrics — in a guided sequence that takes just a few minutes.
Receive an instant A-F overall grade backed by individual component scores. Each result is explained in plain language so both buyers and non-technical sellers can understand exactly what was found.
Generate a tamper-proof verified report sealed with a cryptographic signature. Share it via QR code, link, or AirDrop. Buyers can verify the report is authentic at lorislab.fr/verify.
Maximum capacity, charge cycle count, charging health, and peak performance capability. Detects batteries near end-of-life before they become a problem.
Dead pixel detection, touch responsiveness across the full screen, True Tone calibration, brightness uniformity, and ProMotion adaptive refresh verification.
Front and rear camera focus, optical zoom, flash, video recording, and image sensor quality check. Detects lens damage, autofocus failure, and sensor issues.
Accelerometer, gyroscope, barometer, magnetometer, proximity sensor, and ambient light sensor — all verified against expected calibration ranges.
Speaker output quality, microphone sensitivity, earpiece clarity, and headphone jack or Lightning/USB-C audio path. Detects muffled speakers and dead microphones.
