GPS Parallelfahrhilfe is a handy Android app designed for small farmers that require a parallel driving aid. The app features an AB-line, simple contour line as well as a recording system for the already worn surface. Additionally, the app has an integrated NTRIP client that has been tested with a uBlox ZED-F9P and various NTRIP casters. The app is free for the liberated Ukraine. However, it is essential to note that this is a demo version that has a running time limit and terminates after the expiration of itself. Therefore, it is advisable to test the demo extensively before purchasing. If you face any problems, the app provides a link to an external Bluetooth app to connect the GPS receiver.

It is crucial to use the app only with an external GPS receiver, and several options are provided in the app. Users can access various options by pressing the menu button on their device. For more information, a small guide can be found under "About..." The developer also provides a user forum for Android versions and several DIY receivers options.
