A very accurate compass with many extra functions:
Spirit level, magnetic field, geo data (location)
Due to the camera function you can directly focus on a point through your device and get the exact cardinal point.
* get the perfect contrast by choosing your own layout colors
* portrait and landscape mode (optimized for tablets)
* shows your location via gps or network
* spirit level: acoustic and visiual feedback (with custom tolerance), decimal places, calibration is possible, x and y values can be swapped
* the strength of the magnetic field is displayed
* the app can be moved to sd card
* many other settings..
- The accuracy of the measurement depends on your device's sensors.
- From time to time it may be necessary to CALIBRATE the compass by drawing an eight in the air with your advice.
- The compass works most accurate when the device is in a complete flat or upright position.
- Avoid magnets and electric fields nearby as they influence the sensors. The magnetic field of the earth ranges from about 30 to 60 micro Tesla.
- The rotation in the horizontal position is measured using the compass, thus the accuracy depends on the magnetic field.
* some bug fixes *
