inclinometer

有了这个程序，你可以测量斜坡和表面的角度。

Measure the angles of slopes and surfaces.

The app measures two angles: rotation around the length of the phone's screen, rotation along the width of the phone's screen.

The unit of measurement is degrees.

By default, when the phone is lying flat on a surface, the angles will be close to zero. This is the "Absolute" mode for measurement.

You can also use the app in Relative mode which takes the current orientation as zero (origin) and measures the difference in angles.
