Comprehensive Diagnostics
35+ hardware tests, one tap
ProofCheck runs a complete hardware health check on any Apple device. Every test produces clear pass/fail results with plain-language explanations so both buyers and sellers know exactly what they're dealing with.

- Display: dead pixels, touch responsiveness, True Tone, ProMotion
- Cameras: focus, flash, zoom, video recording, sensor quality
- Sensors: accelerometer, gyroscope, barometer, magnetometer, proximity
- Storage: capacity, read/write speed, NAND health indicators
- Connectivity: Wi-Fi, Bluetooth, cellular, NFC, Ultra Wideband
- Audio: speakers, microphones, earpiece output quality
- Biometrics: Face ID / Touch ID sensor health (no data captured)
Fraud Detection
13 trust signals that catch fakes
Hardware tests are only half the picture. ProofCheck evaluates 13 fraud detection signals to assess whether a device is genuine, unmodified, and honestly represented. The trust assessment catches red flags that hardware tests alone would miss.
- VPN and proxy detection during scan
- Location plausibility check
- iCloud account status verification
- Restore date and factory reset history
- Model number vs. reported hardware mismatch
- Jailbreak and system integrity detection
- Warranty and AppleCare status lookup
