deviceCheck Pulse vs NoiseRadar

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.

NoiseRadar is a simple iPhone utility that helps estimate the direction of the loudest sound around you and identify the general type of sound. Use Scan 360 mode to find where sounds are coming from, or Listen mode to monitor nearby sound types in the foreground. NoiseRadar measures sound levels locally on your device, combines them with compass heading to estimate which direction had the strongest sound signal, and uses on-device sound classification to label likely sound types. Optional foreground threshold alerts and local share reports help users keep practical notes without recording or uploading audio. NoiseRadar is designed for casual sound-direction estimates, troubleshooting, demonstrations, and general utility use. Results and sound labels are estimates and can be affected by background noise, echoes, overlapping sounds, microphone position, compass accuracy, phone movement, and how slowly the user rotates. Privacy: sound levels, sound classification, compass heading, and recent event history are processed on device. The app does not create accounts, record audio files, upload microphone audio, or send scan data to a developer server.
