Three modes: surface, 360-degree, and 3-in-1 view. - Angle Finder โ€” Measure angles with real-time precision using your device sensors. - Protractor โ€” Full on-screen protractor for quick angle readings. - 3D Angle Finder โ€” Measure pitch, roll, and yaw simultaneously in three dimensions. - Laser Level โ€” Project virtual laser lines through your camera for alignment on any wall. - Ruler โ€” Accurate on-screen ruler in centimeters and inches. - Metal Detector โ€” Use the magnetometer to detect metal objects nearby. - Inclinometer โ€” Measure slopes and tilts with degree accuracy. - Compass โ€” Full digital compass with cardinal directions and degree heading. - Plumb Line โ€” Check vertical alignment with a simulated plumb bob. - Barometer โ€” Monitor atmospheric pressure with the built-in altimeter sensor. BUILT FOR REAL WORK Haptic feedback lets you feel when a surface is level. Turn on the flashlight when measuring in dark spaces. Sound alerts confirm level status without looking at the screen. Calibrate sensors for accuracy on your specific device. One app instead of a toolbox full of separate downloads.
