Ruler, bubble level, compass, protractor & decibel meter in one simple app.
Measure Kit puts the everyday measuring tools in one clean, fast app. No account, no sign-up — open a tool and measure. FREE TOOLS • RULER — on-screen ruler in cm/mm and inches with draggable handles. Uses your device's screen size, with a quick credit-card calibration for extra accuracy. • BUBBLE LEVEL — surface mode (2-axis) and edge mode, degrees shown live, haptic tick at 0.0° and a "set zero" calibration. • COMPASS — heading in degrees with cardinal direction, true or magnetic north, and a calibration hint when accuracy is low. • PROTRACTOR — two draggable arms, angle and reflex angle readout. • DECIBEL METER — live dB with min / average / max and a simple quiet → dangerous scale. MEASURE KIT PRO • AR TAPE MEASURE — point your camera at a surface, tap point A and point B. Measure paths and rectangle areas too (requires ARKit or ARCore). • MAGNETIC FIELD DETECTOR — magnetometer reading in µT with a live graph and a beep when the field spikes. Helps find magnets, steel and iron. • Unlimited history with notes and AR photos, plus CSV / PDF export. Pro is available as an annual subscription with a free trial or as a one-time lifetime purchase. Prices are shown in the app before you buy. PRIVATE BY DESIGN — your measurements stay on your device. Camera, microphone and location are only requested when you open the tool that needs them. Audio is never recorded. All tools are for reference only. The decibel meter is approximate and not a certified sound level meter. The magnetic detector only reacts to magnetic materials.
