The Virtual Laser Level allows you use your iPhone’s camera similarly to a laser level. It also shows angles in degrees. Sometimes situations arise where there is no way to approach the object and determine whether it's level. With your iPhone and this program it will now be easy to. The red axes on the screen will always show true horizontal or vertical. They will help determine if an object is level. The gray axis, aligned with the surface of the object, will determine the angle from horizontal. The small window shows the deflection from horizontal. Measurements are most accurate when you stand directly in front of an object. For convenience of measurement, the intersection of axes can be moved around on the screen.
