Each one starts with a sensor or a habit you already have, and ends with a job someone owns.
The Haywren app
Built for gloves, glare and one bar of signal. Everything syncs when you're back in range.
Most farms are live before dinner. No installer visit and no long contract.
Push a probe into each zone you care about and mount the weather station on a fence post. Every unit pairs with the gateway the moment you switch it on.
Trace boundaries on the map or import the shapefiles your agronomist already has. Name fields the way your crew says them out loud.
A short list of what changed overnight and what needs a person, ranked by how soon it matters. Everything else stays quiet.
I used to drive every pivot at dawn. Now I check one screen, then drive to the two that need me.
Straight answers on hardware, signal, data and cost. More in the full FAQ.
Our own probes and weather station work out of the box. We also read most LoRaWAN soil probes and any SDI-12 sensor through the gateway, and you can import readings from a CSV if your current station has no live feed.
No. Sensors talk to the gateway by radio over about three miles of open ground, and the gateway needs one internet connection at the house or shop. The app keeps 14 days of data on your phone and syncs when you are back in range.
About three hours for a 600-acre farm with a dozen probes. Most of that is walking to each zone. We send a printed placement plan with your kit, and the field team will join a video call while you install if you want company.
You do. Export everything as CSV or shapefiles at any time, share a field with your agronomist from a link, and revoke access with one tap. We never sell farm data or share it with input suppliers.
Plans start at $24 a month, or $240 a year, for farms up to 300 acres. Hardware is a one-time purchase that you own, from $129 for a soil probe. The pricing page has an estimator for your setup.
Free for one full season
Put Haywren on the field you worry about most. We loan the sensors, you keep the readings, and there is nothing to cancel.
Sensors, maps, tasks and your crew in one place. Pick a field or change the range below. This is the screen growers open with their first coffee.
Fields
Built in Iowa, tested in Central Valley heat. Solar powered, no monthly SIM, and repairable with a screwdriver.
Everyone sees the same fields. What they see first depends on the job they do.
A ranked morning brief, a season view of every field, and the costs that come with each decision.
The crew sees their own list with directions, the reason for each job and a place to leave a note or a photo.
Share a field or a whole season with your agronomist or crop consultant. They see the source of every number and can leave recommendations in place.
Bring the probes, maps and records you already trust. Take everything with you if you ever leave.
We never sell farm data or share it with seed, chemical or equipment companies. It is written into our terms.
Every reading, note and boundary downloads as CSV or shapefiles. No support ticket, no fee.
Encrypted in transit and at rest, backed up nightly to two US regions.
A loaned weather station and two probes for a full season. Keep the readings either way.
Six places to start. Pick the one that costs you the most sleep, then add the rest when you are ready.

A typical first year, based on 1,400 farms that went before you.
Two probes and a weather station on the field that worries you most. Learn your refill line before the heat.
Turn alerts into jobs with an owner. Add the pivots, troughs and the people who check them.
Pull samples after harvest, attach the lab reports and sketch next year's plan field by field.
The six rules growers set up most. Pick one to load it into the builder.
Pause a rule for the winter, switch it back on in spring. Nothing is deleted until you say so.
Rules tell people. People run the pumps. That line is deliberate.
Haywren does not open valves, start pumps or move pivots. Your controllers stay in charge of your machines.
Each person sets their own quiet hours. Only frost and flood rules can break through them.
Tap an alert to see the reading, the sensor and the rule behind it, so nobody has to guess.
Start with the recipes, then write your own. Every rule is included in the free season.
Every plan starts with a free season on one field, sensors included on loan. Pay yearly and two months are on us.
Prices in USD before sales tax. Cancel any time; yearly plans are refunded pro rata.
A one-time purchase that you own. Most farms need one gateway, one station per 1,000 acres and two probes per irrigated field.

The Haywren Almanac: what our field team saw this month, one practical how-to, and nothing you need to unsubscribe from twice.
Haywren started in 2019 on a dairy in northeast Iowa, with a notebook full of soil readings nobody could find again.
Ines Varga grew up milking cows on her family's dairy near Decorah. When she came home after a decade in software, the farm had more data than ever: probe readings in one app, rainfall in a spiral notebook, lab reports in a shoebox. Nobody could answer the simplest question on a dry July morning: which field needs water first?
She and Kofi Mensah, a sensor engineer she met at a soil science field day, built the first version in the machine shed. It did one thing. It told the family where to look before they left the yard. Twelve neighbors asked for it that winter.
We are still a small company, about forty people between Ames and Fresno. Most of us have mud on our boots more often than we have meetings.
Fields are named the way your crew says them. The software learns the farm, not the other way round.
Every number links back to the sensor, the lab report or the person who recorded it, with the date.
We suggest and remind. We never dress a guess up as a measurement, and we never run your equipment.
First probes on the Varga dairy. A spreadsheet becomes an app.

Account details you give us (name, email, phone, farm name), readings from sensors you connect, field boundaries, tasks, notes and photos your team adds, and basic app diagnostics such as crash reports and the app version.
To run the service: show readings, send alerts and the morning brief, keep your team in sync and support you when something breaks. We use aggregated, anonymous sensor statistics to improve calibration. We do not build advertising profiles.
People you invite, advisers you share a field with, and a short list of processors that host and deliver the service under contract. We never sell farm data or share it with seed, chemical, lending or equipment companies.

Haywren provides software and optional hardware for recording and viewing farm conditions and coordinating work. It supports decisions; it does not make them, and it does not control equipment.
One field per farm, for one growing season of up to seven months. Loaned hardware is returned in the prepaid box within 30 days of the season ending, or bought at a 25% discount.
Purchased hardware is yours. It carries a two-year warranty against defects; in season we ship replacements the same working day.
Plans renew monthly or yearly until cancelled. Yearly plans are refunded pro rata for unused whole months.
Weather data and forecasts come from your station and public models and can be wrong. Always check conditions on site before spraying, irrigating or moving animals.
