If you need to indicate whether a specific surface is even, the application The Best Level was designed for you! With this virtual instrument, functioning the same as it’s real physical equivalent (also known as libella, spirit level or bubble level), you can easily check if the measured surface is truly even. Different types of spirit levels may be used by carpenters, stonemasons, bricklayers and other building trades workers, surveyors and metalworkers. The Best Level beside the classical measure level contains also the calibration option and the bull's eye level (also known as circular bubble) which measures the level simultaneously in two dimensions – horizontal and vertical. If measured surface is even, the ball shown on screen will became red. If surface is unlevel, the ball will remain gray and will be situated outside the center of viewfinder. We recommend our application The Best Level for all users who appreciate precision tools!
