Now it doesn’t work at all. Crashes on startup. ### 5/5 — Great app *2016-10-13* 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. ### 5/5 — About time! *2016-02-25* This app is awesome! So glad someone finally figured out an easy way to calculate this stuff and eliminate wasting my stuff. Couldn't be easier. Highly recommend getting this for anyone who uses a sprayer! ### 5/5 — Great App *2016-02-05* This is a great app! It allows any person with any situation spray more accurate and minimize's chemical loss and maximize spraying results. ### 5/5 — Great tool *2016-01-28* 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. ## Frequently asked questions about Spraying Simple by Master Mfg. ### What is Spraying Simple used for?
