deviceCheck Pulse vs TrueDetect Device Test

deviceCheck Pulse is a professional hardware diagnostic tool built for device technicians and repair professionals. While Pulse can be used as a standalone solution to quickly scan any iPhone and generate a detailed pass/warn/fail report, it is designed to work alongside deviceCheck Studio, our desktop mobile device diagnostic suite for Windows and macOS, providing a complete device testing and reporting workflow. WHAT IT TESTS • Display: cycles solid colors to reveal dead pixels, burn-in, or cracks • Touch Grid: maps the entire digitizer surface for dead zones • Multi-Touch: verifies simultaneous touch point detection • Spatial Control: confirms 3D gesture input via pinch and rotation • Proximity Sensor: detects hand coverage near the earpiece • Volume Buttons: confirms Up and Down button registration • Flashlight: verifies rear LED torch activation • Face ID / Touch ID: tests biometric authentication hardware • Cameras: tests front and rear cameras, autofocus, and flash • Audio: tests bottom speaker, earpiece, and microphone level • Motion Sensors: accelerometer and gyroscope via tilt-ball game • Sensors: barometer, ambient light, LiDAR, and pedometer • Vibration: haptic motor confirmation • Bluetooth: BLE radio scan for nearby devices • Wi-Fi: nearby network detection • NFC: chip presence and response • GPS: satellite fix attempt with accuracy and time-to-fix • Phone: carrier call test via *611 RESULTS Each test produces a clear Pass, Warn, or Fail result. The summary screen shows total tests ran, passed, and failed. Detailed metrics are available for every test. DESIGNED FOR PROFESSIONALS Pulse integrates with the deviceCheck Studio desktop suite for remote-initiated scans, or runs standalone via manual start.

TrueDetect Device Test checks the hardware of an iPhone and reports exactly what it measured. Tap Full Test and the app works through the device one function at a time: display and touch, front and rear cameras, speaker and microphone, vibration, buttons, Wi-Fi, Bluetooth, NFC, GPS, the motion sensors, the compass, the proximity sensor, charging, and the battery. Each check ends in a clear result you can read at a glance, and every card can be opened to see the underlying measurement behind it. Two things guide the whole app: REAL READINGS, NEVER GUESSES A value is shown only when the device itself reports it. Where iOS does not expose something, the app says so instead of filling the gap with an estimate. A result you cannot trust is worse than no result. A FINDING, NOT JUST A VERDICT When a check does not pass, the app states what it found - which part, and what was measured - so the reason is on the screen rather than left to memory. Any test can also be run on its own from Manual Test, which is useful when you want to re-check a single function after handling the device. The app is made by K-Device Lab for businesses that inspect used iPhones and need an honest, repeatable record of a handset's condition. It is free, contains no advertising, and offers nothing to purchase.
