Best AI App for Farmers: Herdwatch, AgriWebb and Farmonaut Compared

For a small livestock farm, choose between Herdwatch and AgriWebb by region first: Herdwatch runs Irish, UK and US sites and has an in-app AI assistant, while AgriWebb runs Australian, UK, US and South African sites. For crops, Farmonaut is the AI choice, priced by hectares from $4.99 a month.

One caution about the title. Herdwatch and AgriWebb are record-keeping apps first. Herdwatch has added Herd Intelligence, an AI assistant that answers questions from your own herd records, while AgriWebb's pages describe records, reports and grazing tools, not AI. Farmonaut is AI-driven throughout (satellite imagery plus advisories). So the real question is which farm app earns its fee, with AI as one factor and not the whole story. Check each vendor's current price on your own herd or acreage.

What each app actually does

Herdwatch is a livestock record app for cattle and sheep, with pasture and grazing tracking. Its US pricing page says you can record cattle moves, weights and herd notes offline and sync later, and shows two tiers, PRO for record keeping and PRO+ for breeding, health and performance insights. Prices are not printed: you request a quote based on farm type and herd size, and the UK site uses different plan names (Essentials, Complete and Innovator). Herdwatch also describes Herd Intelligence, an AI farm assistant inside the app that answers questions from your herd, breeding and compliance records and, by its own account, does not learn from your data. Its pages do not say which plan includes it, so ask.

AgriWebb is a livestock and cropping records system with three packages. Essentials covers an interactive farm map, mob or individual animal records, livestock reconciliation, tasks and drag-and-drop mob movements. Compliance adds audit and biosecurity tools, treatment and weight records, feed management, joining and pregnancy scan records and cropping records. Performance adds weight projections, grazing management, more breeding and fertility reporting, financial reporting and a stocking-rate report. Its pricing page works through a calculator that asks for cattle and sheep numbers and shows prices before tax.

Farmonaut is different in kind. It monitors fields from satellite images and gives irrigation, pest and disease, and nutrition advice and yield forecasts, with history from 2018. Its pricing page lists tiers by hectares and says every plan runs the same satellite engine, with what changes being how much land it watches.

The region question comes first

A livestock app is only as useful as its fit with your local rules: how animals are tagged, how movements are reported, which assurance schemes audit you. Herdwatch runs separate Irish, UK and US sites, with plan names that differ by site. AgriWebb's main site is Australian, with UK, US and South African versions. Both lists come from the vendors' own site menus, which say where they sell, not which official systems they connect to in each country. If you farm somewhere else, ask each vendor in writing which official database or scheme the app talks to, rather than assuming.

The practical test: before you pay, enter ten real animals, a movement and a treatment, then ask a person who knows your reporting rules whether the output is what an inspector would expect. Free trials exist for the livestock apps, but check the length, because I could not confirm a standing free plan on either.

Prices as far as they can be verified

Farmonaut's annual option is described on the page as two months free, and the figures are shown in dollars, with a note that each plan bills in its own currency and taxes may apply. Standard works out at about $0.81 per hectare a month and Premium about $0.75, so the per-hectare cost falls as the area grows. For the two livestock apps, run the calculator or request the quote with your real numbers, and write down the figures with the date. Do not trust any price older than a few weeks.

A worked choice for a 150-head suckler herd

Illustration, with made-up numbers. A farm runs 150 beef cattle and 40 ha of grass and forage. The owner currently keeps tag numbers in a notebook and treatments on a wall calendar. The jobs that cost time are: recording weights at handling, proving treatment dates to an assurance auditor, and tracking which paddock each group is in.

1. Job list by pain: audit paperwork (4 hours a quarter at present), weight records (2 hours a month), paddock tracking (1 hour a week).
2. Apps that fit: a livestock records app for all three, matched by region. Farmonaut would add little, because forage is a small part of this farm.
3. Cost sum: if the quote is, say, $400 a year, and the app saves 12 hours a year of audit and weight paperwork at $25 an hour ($300) plus easier proof when a buyer asks about treatments, the gain is thin on time alone. The case rests on audit confidence and a cleaner record, so ask yourself whether you value those.
4. Decision: take the free trial from the app that serves your region, enter one week of real records, and keep it if the audit report comes out in a form you can hand over.

That sum is deliberately unimpressive. Small-herd software rarely pays for itself in saved hours. It pays when it prevents a failed audit, a lost premium or an animal sold within its withdrawal period, which is an event you can price from your own history.

A worked choice for an 80-hectare arable farm

Another illustration. An arable farm of 80 ha in 14 fields has no livestock. The owner wants earlier warning of patchy crop areas and a record of what was done where.

1. Farmonaut's Standard plan covers 80 ha for $64.99 a month, or about $650 a year if the two-months-free annual option applies, and allows 56 land parcels (the farm needs 14).
2. The plan includes irrigation, pest and disease, and nutrition advice plus yield forecasts, and the page says history from 2018 is included.
3. Test it on two fields the owner knows well. If the satellite view flags the patch the owner already knew about, that is a good sign. If it misses a problem the owner saw on foot, the tool is a prompt, not a replacement for walking the field.
4. The page claims farmers using it cut irrigation and fertiliser use by up to 50%. That is the vendor's own marketing statement, so I would treat it as unproven for your farm and judge by your own two-field test.

The decision rule that falls out is simple: if the money is in animals, buy a records app; if it is in crops, test satellite monitoring on two fields before you scale it to the rest.

Five jobs and which tool takes them

• Proving treatments and movements to an auditor: Herdwatch or AgriWebb, depending on region. Neither is a substitute for official reporting systems unless the vendor says so for your scheme.
• Spotting fields that need attention: Farmonaut. Use its advisories as prompts to walk the field.
• Drafting a summary email to a vet or buyer: a chat assistant. Paste the exported record and ask for a one-page summary, then check it against the source.
• Keeping staff and tasks straight on a busy week: the team and task tools in AgriWebb's Essentials, or the rota ideas in AI automation for farm rotas and timesheets.
• Farm accounts and margins: your accounting software, not the farm app. The tutorial on farm accounting software with AI covers where the line falls.

Using a chat assistant beside the app

A general chat assistant earns its keep on writing and sorting, not on holding records. A prompt that works after you export a weights report:

Here is a CSV of weights for 38 weaned calves with two weigh dates each.
Calculate daily liveweight gain per animal, list the five lowest, and
suggest what I should check about those animals. Do not give treatment advice.
Show the arithmetic for any figure you present.

A realistic sample output (illustrative) lists the five slowest gainers with their daily gain in kilograms and a few sensible prompts: check for lameness, look at the group's feed access, compare with the same animals' last gain. What you fix: check two of the sums by hand (assistants sometimes misread dates) and delete any line that sounds like diagnosis. The tutorial on ChatGPT, Claude or a farm app goes into that split further.

On Herdwatch, put the same question to Herd Intelligence first, since it reads your records without an export. Then check its answer against the export sum for two animals. If the two disagree, trust neither until you find out why: a missed weigh date or a duplicate tag is the usual cause, and it will distort every report the app produces, not only the AI's answer.

A worked choice for a 600-ewe flock

A third illustration, because sheep work differently from cattle. A flock of 600 ewes lambs over five weeks in spring. The busiest recording moments are lambing (births, losses, fostering), a pre-sale weigh and a worm-egg count decision in summer. Records are taken in a wet shed with a phone in one hand.

1. Pain list: lambing records on scraps of paper that get lost; no record of which ewes needed help; a summer treatment decision made by habit, not evidence.
2. Features to look for: mob or individual recording, offline entry, joining and pregnancy scan records, and treatment history. AgriWebb's Compliance package lists joining and pregnancy scan records, treatment and weight records, and a worm test record. Herdwatch lists sheep management as a separate solution on its site.
3. Test: record one night's lambing in the app and on paper. If the app takes you more than about 30 seconds per lamb in a tired state, it will be abandoned by week two.
4. Check the output: at the end of lambing, export a report of lambs born, lost and fostered per ewe group. If you can read your lambing percentage straight from it, the app has done its main job.

Notice what the example does not claim. It does not say the app lifts your lambing percentage. Records tell you what happened; the decisions are still yours and your vet's.

A mixed farm: one app, two apps, or neither

A mixed farm of 60 cattle and 120 ha of arable has two different record problems. Cattle need animal records and movement reporting; arable needs field records and early warning. Pricing the combinations is the honest way to decide.

• Livestock app only: cheapest, and fine if the arable is a stable rotation that you know field by field.
• Farmonaut only: sensible if the cattle numbers are low and the records are already adequate on paper.
• Both: at 120 ha, Farmonaut's Premium (300 ha, $224.99 a month) is more than you need and Standard (80 ha) is less, so ask Farmonaut's team about a bespoke plan between the two before you pay for unused area. Add the livestock app quote, and compare the total with what one hour of avoided crop or audit trouble is worth to you.
• Neither: a spreadsheet, a free chat assistant for summaries and the discipline to enter data weekly. This is a legitimate answer for a very small holding.

Questions to ask each vendor, filled in

A blank question list is easy to ignore, so here is one already written as an email. Copy it, replace the square brackets and send it to all three vendors; the answers go straight into a comparison table.

Subject: Question before we start a trial

Hello, we run [150 suckler cows and followers] on [90 ha] and keep records by hand.
Before we trial your app, could you confirm in writing:
1. Which of our official reporting or assurance systems does it connect to, if any?
2. What is the price for our numbers, per year, excluding tax, and what is not included?
3. What happens to our data if we cancel: can we export every record as a spreadsheet?
4. Which features are AI-driven, on which plan, and how are they limited?
5. Can two staff members use one account at the same time?
Thanks, [your name]

Treat a vague answer to question 3 as a warning. Records are years of work, and the right to take them with you is worth more than any single feature.

A data-ownership checklist

• Can you export animals, movements, treatments, weights and notes as a spreadsheet, not only a PDF?
• Does the export keep tag numbers, dates and units exactly as entered?
• Who owns the data in the terms, and can the vendor use it for anything beyond running your account?
• Is there a limit on how long records are kept after you cancel?
• Can an adviser or vet see the records without sharing your password?

For Farmonaut, whose data is mostly your field boundaries and the imagery of them, the questions that matter are different: who owns the boundary file you upload, and whether the history from 2018 that the page mentions can be downloaded for your fields. Ask in writing.

Before and after: a treatment summary for the vet

A chat assistant is good at turning a messy export into something a vet can read quickly. Suppose the app export gives lines like "12/10 Ewe 0431 Footrot Spray; 14/10 Ewe 0431 Lame, checked". A first draft from a vague prompt may restate every line and add advice. Give it a tighter instruction instead.

Summarise these treatment records into one table: tag, date, problem, action.
Then list tags with more than one entry in 14 days.
Do not suggest causes or treatments. Flag any line you could not parse.

The output (illustrative) is a clean four-column table, a short list of repeat cases and a flagged line where a date was written as "last Tuesday". That flag is the useful part: it shows you where your records are weak. The fix is a rule at recording time ("always enter the real date"), not a smarter prompt.

What a farm year looks like with the right tools

Seasonal timing decides when an app pays back, so map your year before you buy. A livestock farm is busiest at calving or lambing, at weaning and at sale time; a free trial taken in a quiet month tells you little. Start a trial just before your busiest recording period, not after it. An arable farm's pressure points are drilling, the spring growth flush and harvest, so trial Farmonaut across a growing period and compare its alerts with what you saw in the field.

A practical calendar for a mixed farm: choose in the quiet months, trial through the first busy month, decide before the next busy month, and review again at year end. Seasonal staff also matter: if two people record in the pen and one keys data at the kitchen table, check the app handles multiple users at once without duplicate animals appearing.

Four ways farm apps disappoint

• The empty fields. An app is only as good as the records you enter. A farm that skips weights for a month ends up with a report that shows nothing. Choose the app whose recording step is quickest at the handling pen, and test it with gloves on.
• The reporting gap. Some apps record movements but do not file them with an official system, so you enter the same thing twice. Ask what is automatic and what is not.
• The signal gap. Offline use matters in a remote field. Both livestock apps advertise offline recording, but test it with the phone in flight mode before relying on it.
• The advisory trap. Satellite advice can say a field is stressed without telling you why. Treat each alert as a reason to look, not an instruction to spray.

How to run a two-week trial properly

1. Pick one real task per day: a weigh, a treatment, a paddock move, a sale. Do it in the app and on paper.
2. At the end of the first week, compare the app's report with the paper. Note every mismatch.
3. In week two, ask the person who does your audits or advises you to look at the exports.
4. Write down the minutes each task took in the app compared with the notebook. If the app is slower after the second week, it will be slower in the next year.
5. Only then ask for the full quote, with your real animal or hectare numbers, and put the answer in a note with the date.

Questions before you pick a farm app

Do Herdwatch and AgriWebb use AI?

Herdwatch does: it describes Herd Intelligence, an in-app AI assistant that answers questions from your own herd, breeding and compliance records. AgriWebb's pages present it as livestock record and performance software, without AI features. Before paying for either, ask which plan includes any AI feature you want. Farmonaut is the most AI-driven of the three.

Can I use one app for cattle and for crops?

Not well. The livestock apps cover animal records and, on some plans, cropping records. Farmonaut watches land from satellite images and advises on irrigation, pests and nutrition. A mixed farm often ends up with one of each, so price both before deciding they are one purchase.

What if my region is not listed?

Livestock apps depend on local tag rules, movement reporting and audit schemes. If your region is not one a vendor lists, ask in writing which official systems it connects to, and run a free trial with real animals before you commit. Satellite monitoring is less region-bound, since images cover the world.

Is a free ChatGPT or Claude chat enough instead?

A chat assistant can tidy notes, draft treatment summaries and explain reports, but it does not hold your herd register or file official movement reports. Use it beside an app, not instead of one, and never rely on it for withdrawal periods or dosing.
