Spray Mix: Dilution & AreaSupport
Need help with Spray Mix? Whether a dilution result looks off, a plot won't measure, or you have a question about powders and spoon settings, we're glad to help. Take a look at the FAQ below first — it covers the most common questions — and if you're still stuck, send us an email and we'll get back to you.
FAQ
How accurate is the area measurement?
Map tapping is as accurate as the points you place — zoom in close and tap each corner carefully for the best results. GPS walking depends on your phone's GPS signal, which is typically within a few metres outdoors. That's more than enough for spraying and feeding jobs, but for legal or property-line purposes, always rely on an official survey.
Does Spray Mix work offline?
Yes. All calculations, saved products, and saved plots work with no connection at all. The satellite map needs an internet connection the first time you view an area; once it's loaded, you can keep working offline — a real plus on rural properties with no cell service.
How do I measure powders without a scale?
Switch the product to powder and Spray Mix shows the amount in grams, along with the equivalent in teaspoons and tablespoons. Since powders vary in density, you can set how many grams your teaspoon holds for each product — weigh one spoonful once, enter it, and every calculation from then on uses your number.
The label says something different from the app. Which do I follow?
Always follow the product label. Spray Mix is a calculator: it converts the ratio or rate you enter into quantities, but the label is the law. Read and follow the label's rates, safety directions, and restrictions, and use the app's results only within what the label allows.
Where is my data stored?
Everything — your products, ratios, plots, and plans — is stored only on your iPhone or iPad. Nothing is uploaded, there's no account, and we can't see your data. Deleting the app deletes the data along with it.
