<p><i>Basic Air Data Clinometer</i> is a simple App to measure your device’s inclination angles with respect to gravity’s direction using the onboard accelerometers. It is a basic and lightweight App with geometric-inspired graphics that can be used as Clinometer or Bubble Level. It is intended to measure, not store data.</p><p>A „Getting Started“ guide <a href='https://www.basicairdata.eu/projects/android/android-clinometer/' target='_blank' rel='nofollow'>can be found here</a>.<p><b>IMPORTANT NOTE:</b> Please go to Settings and calibrate it before use. The measurement’s precision mainly depends on the accuracy of the calibration: use a good horizontal and vertical reference.</p><p><b>USAGES:</b></p><ul><li>Bubble Level (horizontal)</li><li>Clinometer (vertical)</li><li>Measure with the Camera (vertical only)</li></ul><p><b>MEASUREMENT:</b></p><ul><li>X (Yellow) = The angle between the horizontal plane and the horizontal axis of the screen</li><li>Y (Yellow) = The angle between the horizontal plane and the vertical axis of the screen</li><li>Z (Yellow) = The angle between the horizontal plane and the axis that comes out perpendicular to the screen</li><li>Pitch (White) = The angle between the contour line (inclined, white) and the reference axis (horizontal or vertical, dashed white) on the screen plane</li><li>Roll (White) = The angle between the screen and the horizontal plane</li></ul>
