Sensor Toolkit

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.
