Our free app

In your cab, our free Agricision onTrak app turns your Tablet or Phone into the onTrak control centre

Our free app works with Android phones and Tablets as well as Apple iPads and iPhones. For the best experience we recommend using onTrak with a tablet as the screen is larger. Although a phone works well too.
The app is used to setup the machine working width, generate straight and curved guidance lines, map area worked, measure fields and much more.
