SIKUCONTROL App
Please check the data sheet of your device or the manufacturer's website to see whether your smartphone/tablet has a gyro sensor or a gyrometer. The gyro sensor is a position or acceleration sensor that reacts to the rotational movements or changes in position of your device. Only devices with a gyro sensor can be operated using the Motion Sense control.

We recommend using the app at least occasionally. This way you can check whether your model is up to date or update the software. The APP also offers functions such as fine adjustment of the steering and much more.
