Bubble Level

This application will help you to determine if a plane or a surface is in a perfectly horizontal (at level) or vertical (plumb) position. Hold any of the phone's four sides against an object to test it for level or plumb, or lay it down on a flat surface for a 360° level. The Bubble Level Tool, Leveler app, also serves as a goniometer or a carpenter’s level and can be applied in construction, carpentry, photography as well as daily life. It mimics and works like a real level meter. It is very handy and useful to provide you with accurate results.
