About this app

A bubble level, spirit level or simply a spirit is an instrument designed to indicate whether a surface is horizontal (level) or vertical (plumb). Bubble Level app is handy, accurate, simple to use and incredibly useful tool for your Android device.

A traditional modern level meter has a slightly curved glass tube which is incompletely filled with a liquid, usually a colored spirit or alcohol, leaving a bubble in the tube. At slight inclinations the bubble travels away from the center position, which is usually marked. Bubble Level app tries to mimic the real level meter and displays the data as real level meter would.

Bubble Level app also features a bull's eye level meter which is a circular, flat-bottomed device with the liquid under a slightly convex glass face with a circle at the center. It serves to level a surface across a plane, while the tubular level only does so in the direction of the tube. Bubble Level app tries to mimic the real bull's eye level and displays the data as real bull's eye level meter would.
