Food plot guy ,

Great app

I like that you can use Google Earth to find where you are spraying, and the app automatically calculates how much liquid you will need to spray it. I hated using too much Round Up on my food plot and wasting money! Or even worse running out before you're finished and going back the next day!!! That's the sort of mistake you only make once lol.

This app is easy, and saved me money. It's kinda fun to use too once you get the hang of it.

Great tool

Great tool to help with spraying. You can save your properties and equipment with notes. I never know if I am going the correct speed so the speedometer function is also helpful.
