PhoneCheck Pro vs Sensor Toolkit

evice Monitor is a fast, no-nonsense hardware inspection tool for iPhone. Whether you're buying or selling a used iPhone, or just want to verify that everything works on your current device, Device Monitor walks you through 8 essential checks in about 3 minutes. WHAT IT CHECKS • Screen Colors — Full-screen color patterns to reveal dead pixels, tint, burn-in, and bright spots • Touch — Interactive grid to confirm the display responds evenly, including edges and corners • Camera — Front and rear camera availability and live preview check • Flashlight — Hardware torch toggle test • Microphone — Short audio recording with instant playback • Speaker — Audio playback test using the built-in speaker • Biometrics — Face ID or Touch ID hardware support check • Connectivity — Wi-Fi, Bluetooth, battery level, charging status, and vibration HOW IT WORKS Each step gives a clear one-line instruction and three result buttons: Pass, Issue, or Skip. Automated steps run on their own — you just confirm the result. After all 8 steps, you get a clean summary showing exactly what passed and what needs attention. HONEST ABOUT WHAT IT CANNOT DO Device Monitor does not claim to verify original parts, Apple's official battery health, board-level faults, or IMEI/carrier lock status. It focuses on the hardware checks an ordinary user can meaningfully confirm in a trade situation. NO ACCOUNT REQUIRED Everything runs locally on your device. No sign-in, no cloud sync, no data collection.

Sensor Toolkit turns your iPhone into a clean, practical set of everyday measurement tools. Use it when you need a level, compass, vibration meter, magnetometer, heading reader, sound meter, ruler, protractor, timer, or metronome without switching between separate apps. Built for quick checks, field work, DIY tasks, practice rooms, and daily utility, Sensor Toolkit keeps each tool focused on the measurement in front of you. Key features: • 10 tools in one app Level, Compass, Vibration, Magnetometer, Heading, Sound Meter, Ruler, Protractor, Timer, and Metronome. • Real-time sensor readings Clear visual feedback helps you read tilt, direction, sound level, vibration, magnetic field strength, angles, time, and tempo at a glance. • No ads while measuring Measurement screens stay clean, focused, and distraction-free. • Sound and vibration logs View live measurement changes over time and save chart images when you need a record. • Practical instrument-style design Dark, high-contrast screens make readings easy to check quickly. • Privacy-conscious permissions Permissions are requested only when a tool needs them. Microphone audio is used for sound level measurement and is not saved by the app. Sensor Toolkit is designed for practical reference measurements. Results depend on your device sensors, calibration, and environment, so it is not a replacement for certified professional measuring equipment.
