LevelRule

LevelRule puts a bubble level, an on-screen ruler, and a touch protractor in one place for quick checks around the home, workshop, or job site.

• Read live pitch, roll, and total tilt on a clear bubble gauge

• Set any surface as zero to compare against an existing slope

• Measure small objects on the screen in millimeters or inches

• Calibrate the ruler with a credit card, a one-inch mark, or any object of known length

• Drag two protractor arms to measure the angle between them

• Save labeled readings with notes, reload them later, and share the results

Ruler accuracy depends on your screen, so calibrate it once for more accurate readings.
