Hay, tracked properly
Cuts, movements between farms, and feed-out — so you know what's left in the shed.
Free to start — no credit card required
Every mob, every paddock,
every millimetre of rain.
BlackCow keeps your cattle, paddocks, rainfall, spraying, sales and reports in one place — built by someone who actually farms, for the work you actually do.

See it in action
Real screens, not a demo reel
Every image below is a real screenshot of the running app — a fictional "Willow Creek" demo farm, not your data, but the actual screens.
Weather & rainfall — the flagship
One rainfall number you can defend at the pub
Drop your GPS coordinates in and BlackCow finds the weather stations around you — the BOM one, and the Weather Underground gauges your neighbours paid good money for. It plots the nearest few, does the distance-weighted maths, and works out what actually fell on your place. Read your own gauge? That wins, every time. Haven't read it yet? The blend fills in behind it. Your neighbour's $3,000 weather station is now your weather station too.
Rainfall analytics
The hundred-year conversation, with receipts
Year-over-year comparison, monthly distribution, record years, a drought decile gauge, wet/dry streaks — the numbers you'd otherwise be guessing at from memory over the fence.
Cattle & mobs
Every mob, with real numbers behind it
Head counts, paddock location and movement history — reconciled against your Stock Numbers automatically, so "all accounted for" is a fact, not a guess.
Stocking rate & grazing days
Know before you're overgrazed, not after
DSE load against paddock capacity, per paddock, against the same MLA benchmarks a consultant would use — done automatically from your mobs.
Spraying, treatments & WHP
Audit-ready without trying
Import the GPX track off your GPS and the actual boom pass is right there on the map — real hectares and distance driven, not an estimate. Every treatment carries its withholding and export slaughter interval automatically too.
Siri voice logging
It lands in the app before you're back at the ute
Say "Hey Siri, log farm note — 14 mil in the gauge and moved the weaners to River Flat." It lands as a draft on your Dashboard, Claude turns it into a structured record, and you approve it before anything writes to your data. It doesn't guess silently — nothing saves without your say-so.
Connection token redacted — it's a private credential, same as a password.
Sales, market prices & herd value
Know what your herd is worth, today
Live MLA saleyard indicators priced against your actual mobs, plus every sale on record — revenue split across farms automatically when a mob spans more than one.
Reports & season snapshots
This year against last, without the spreadsheet
Sales, rainfall and herd events roll up automatically so you can see whether the season's ahead or behind — not reconstruct it in a notebook in June.
What's inside
Everything a serious operation needs
No modules to bolt on later. It's all here from day one.
Fertiliser jobs & quotes
Track jobs against paddocks, log supplier quotes, and send a quote request without leaving the app.
Calving & marking tallies
Steer/heifer ratios and season summaries, recorded as you go rather than reconstructed in June.
Preg testing
Log results as the vet calls them, with history per mob for next season's decisions.
Alerts centre
One feed for everything due or overdue — services, withholding periods, key dates — instead of six.
Assets & service reminders
Tractors, motorbikes and pumps — with editable service history and hours/km tracked by year.
Pastures & paddock condition
Condition notes and alerts alongside the weather data that actually explains them.
Multi-farm, multi-user
Run more than one property, invite a worker with their own login and role — no shared passwords.
Works where you work
Installable PWA, built mobile-first, usable one-handed with gloves on a fence line — offline too.
The rhythm of it
How it fits your year
01
Set up farms and paddocks
Draw your paddocks, add your mobs, set your weather stations. Ten minutes, once.
02
Log as you go
Calving, marking, drenching, spraying, rain — enter it from the paddock, or tell Siri and let it land in the app.
03
Watch the season build
The dashboard and reports fill themselves in — head on hand, rain to date, spend by paddock.
04
Roll over and compare years
Close out the season, start the next, and see how this year stacks up against last.
