Dual Level is a two-dimensional level instrument, that is, you can not only use it to measure lines, but you can also use it to measure surfaces.

Dual Level has a calibrate button so that you can measure two lines to compare if they are on the same level, or you can measure two surfaces to compare if they are on the same plane.

There is also a app call Dual Level Pro which can save and load calibrations that you have ever used.
