How to use the Bubble Level:
The Bubble Level also simulates a bull’s eye level, which levels across a plane. To determine whether a surface is horizontal or vertical, or to measure its inclination angle, you can simply lay your phone flat on the surface, or lean the phone against it.

This leveler app indicates horizontal when the bubble is in the middle. It will show the actual angle in the meantime. Thanks to its sound effects, you can hear the result without looking at the screen.
