Details

Attention:
Unfortunately, the app keeps getting bad reviews because the compass or spirit level doesn't work. This is then because the device does not have a compass sensor or a tilt sensor. An understanding from the buyer is very rare. A refund is of course possible. So please convince yourself before buying whether your device has the following sensors.

-Compass sensor
-Tilt sensor
-GPS
