Please open and read the full description...


A simple parallel driving aid for the small farm, with AB-line, simple contour line and recording the already worn surface.

In order to be able to use correction services, an NTRIP client has been integrated (tested with a uBlox ZED-F9P and various NTRIP casters).

The app is free for the liberated Ukraine!

Attention: This is a demo, the demo has a running time limit and terminates after the expiration of itself. Please test the demo extensively before buying! If you have problems please use the external Bluetooth app to connect the GPS receiver: https://play.google.com/store/apps/details?id=googoo.android.btgps

2. Click repeatedly on "Build number" until a message appears
3. Now you have a new menu item "Settings / Developer Options"
4. Here you can then "Allow mock locations" to enable (or also "Simulated locations")
