About this app
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: measure angles 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.
