This level is an instrument designed to indicate whether a surface is horizontal (level) or vertical (plumb). Different types of spirit levels may be used by carpenters, stonemasons, bricklayers, other building trades workers, surveyors, millwrights and other metalworkers, and in some photographic or videographic work.

Our App include the capability of:

* Level Measure
* Calibration for Horizontal and Vertical.
* Hold a Measure
* Auto-rotation of buttons and titles of the App.

Early tubular spirit levels had very slightly curved glass vials with constant inner diameter at each viewing point. These vials are incompletely filled with a liquid, usually a colored spirit or alcohol, leaving a bubble in the tube. They have a slight upward curve, so that the bubble naturally rests in the center, the highest point. At slight inclinations the bubble travels away from the marked center position. Where a spirit level must also be usable upside-down or on its side, the curved constant-diameter tube is replaced by an uncurved barrel-shaped tube with a slightly larger diameter in its middle.

Where can you use Bubble Level?

A bubble level is usually used in construction, carpentry and photography to determine if objects on which you're working on are level. Used properly, a bubble level can help you create flawlessly leveled pieces of furniture, help you when hanging paintings or other items on the wall, level billiard table, level table tennis table, set up a tripod for photographs, level your trailer or camper and much more. It’s a must have device for any home or apartment.
