DeviceScope Test vs TrueDetect Device Test

DeviceScope Test is an all-in-one hardware diagnostic and sensor testing toolkit for iPhone and iPad. Quickly check essential components, view live readings, and troubleshoot common device issues from one clean workspace. WHAT YOU CAN CHECK • Audio — Monitor microphone input, test speaker playback, and check volume controls. • Camera — Preview your camera, test the flashlight, and detect AR support. • Display & Input — View screen resolution and pixel density, check touch response, adjust brightness, and use fullscreen colors to look for dead pixels, stuck pixels, or light bleed. • Sensors — Inspect accelerometer, gyroscope, compass, barometer, proximity, ambient light, and pedometer readings. • Connectivity — Check network and Wi-Fi information, scan nearby Bluetooth devices, test NFC, and view GPS accuracy. • System — View battery level and charging status, device information, notification permissions, clipboard behavior, vibration, and biometric capabilities. • Speech — Try text-to-speech and speech recognition tools. USEFUL FOR • Troubleshooting before a video or voice call • Checking a new, used, or repaired iPhone or iPad • Exploring device sensors and hardware capabilities • Running quick QA checks without switching between multiple apps • Finding display, audio, camera, or connectivity problems FAST AND FOCUSED Each tool provides a simple interface with clear status feedback. Open the check you need, follow the instructions, and view the result immediately. PRIVACY BY DESIGN No account is required. Tests begin only when you choose them, and permissions are requested only for features that need them. Your device test results are not uploaded to our servers. Feature availability and readings may vary depending on your device model, hardware, iOS or iPadOS version, permissions, and regional support.

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.
