Tool Box: Compass, Sound Meter

A Tool Box app with nine measuring tools that use the sensors already in your phone. MeasureKit puts a compass, decibel meter, bubble level, ruler, magnifier, protractor, inclinometer, vibration meter and lux meter in one app. No account, no server. Install and measure. WHAT YOU CAN MEASURE - Compass: heading and true north, sunrise and sunset times, altitude. Shows a calibration hint when accuracy drops - Sound meter: live decibel meter in dB(A) with min, average and max, plus a reference chart - Bubble level: three vials for X and Y at a glance, with the angle in numbers - Ruler: calibrate the screen once and measure real lengths in cm, mm and inches - Magnifier: camera magnifying glass with brightness, color inversion, freeze and save - Protractor: an angle meter against the screen, landscape mode - Inclinometer: two-axis tilt for shelves, pipes and ramps - Vibration meter: three-axis acceleration, explained in plain words - Lux meter: light in lux and foot-candles, with recommended levels per room KEEP YOUR READINGS Save a measurement and find it again in the log. Capture the screen and share it as is. Turn on a sound or vibration alert when a reading passes your threshold. BUILT FOR ACCURACY - Tools that need a sensor your phone does not have are hidden, not broken - A phone microphone is not a calibrated instrument. The app says so on screen - Gauge needles are damped so they do not jump - Every tool has a Help button with steps and a short glossary GOOD FOR - Leveling furniture and measuring small things around the house - Putting a number on neighborhood or workplace noise - Hiking and camping: heading, sunrise and sunset - Reading small print English and Korean, light and dark themes. NOTES - This app contains ads. - Readings depend on your device sensors. Use professional equipment for safety-critical decisions.
