Questions

Asked before you start

How is this different from a weather app?

A weather app shows a rain chance per hour. This checks each of your rounds against its label limits and rainfast time in every forecast run, and tells you the share of runs where the whole route works.

Can I keep a record of my rounds?

Yes. Log a window and the decision log keeps the verdict, the share of forecast runs that passed and the conditions the forecast showed, with your note. Export it to CSV whenever you need it.

Does it tell me whether I'm legal under my fertilizer law?

It shows the forecast against the rule you choose. These laws do not define heavy rain in inches, and county rules differ.

What data does it use?

It pools up to 146 forecast runs for your service area from three independent forecast systems, judged run by run and refreshed through the day, plus modelled soil temperature.

Can I change the limits?

Yes. Every limit shows where it comes from; set your own to match your product label.
