spirit levels meter and derection
A traditional modern level meter has a slightly domed glass tube that is incompletely filled with a liquid, usually a bubble or colored alcohol, leaving a bubble in the tube. At slight inclinations, the bubble moves away from the central position, which is usually marked. The Bubble Level free for phone application tries to mimic the actual level tool meter and displays the data as a real level meter.

The real Bubble Level indicator app also has an ox eye level indicator which is a flat-bottom circular device with the liquid under a slightly convex glass face with a circle in the center. It is used to level a surface across a plane, while the tubular level does so only in the tube direction. The Bubble Level application tries to mimic the level of the actual bull's eye and displays the data as a real-level meter.
