About CropWindow
Built on a working farm at Humevale, Victoria
CropWindow is made by Ryan Turner on a cattle and hay farm in the Great Dividing Range foothills. The app answers the same question the farm asks every morning: which job, which day, and how sure are we.
Where it started
Four apps, a rain radar, and a missed window
The morning routine was the problem. Two forecast apps, a wind app, a radar loop, and a gut feel built from years of getting it wrong occasionally — and the spray window still slipped past. The forecast was never the hard part. The hard part was the judgement: this job's limits, against these hours, on this ground.
So Ryan built the operator's judgement into software. CropWindow holds each job's thresholds — wind band, Delta T, rainfast hours, dry days — and matches them against the local hour-by-hour forecast, continuously. The output isn't weather. It's the call: the right day, a red, amber or green confidence, and the reasons behind it.
"I didn't want a prettier forecast. I wanted the sums I was doing in my head at 6am done properly, every hour, for every job — and I wanted the app to show its working."
The test bed
The farm argues back
Every release runs at Humevale first, on the farm's own weather station, against real jobs with real consequences. When a call is wrong, it gets argued with at dinner — and the engine gets fixed before anyone else sees it. That loop is the product's quality control, and it doesn't switch off.
What CropWindow believes
Four rules the product is held to
Answer first
The point of the app is the decision, not the data. You get the day and the window up front; the forecast detail is there when you want to check the working.
Own the uncertainty
Forecasts are probabilities, not promises. CropWindow says how sure it is and why, flags the borderline calls as borderline, and never dresses an amber up as a green.
Your records are yours
Jobs, thresholds and history belong to you, not to the app. If you ever leave, your records export with you — that's a promise, not a setting.
No fake anything
No invented testimonials, no padded user counts, no stock-photo "customers". When you read a number on this site, it's real, or it isn't here.
Used in the field
Working the same district it was written in
CropWindow is used day to day by Oak Ridge Agriculture, the founder's land-services business working the same district — slashing, spraying and property maintenance jobs that live or die on the weather. Client work is a harsher reviewer than any test suite: a wrong call there costs someone else's money.
"If it's wrong at home, we lose a day. If it's wrong on a client job, I hear about it a lot sooner."
