A cattle fence that fits in an ear tag.
A battery-powered ear tag you buy and own. Draw a pasture on your phone. When a cow walks toward the line, her tag sounds a cue. No shock, no lease.
How it works
Draw the pasture
Trace the boundary on a map. It's sent to every tag in the herd.
The tag keeps watch
GPS in the tag knows where she is. It checks more often near the line.
A cue at the line
She walks toward it and hears a cue. Turn back and it goes quiet.
The tag decides on its own when to cue, so the fence works without cell service. If one gets out, you get an alert. It's for moving cattle between pastures, not for keeping them off a road, so keep your boundary fences.
Rotate pastures on a schedule
Pick the paddocks and the days in each. When it's time, the gate opens, the herd walks to fresh grass, and the fence closes behind them.
It waits for every cow before it closes. A paddock that needs more rest stays shut.
Built for how you run cattle
- An ear tag. Any hand can put one in.
- Built to run a grazing season on one battery. Swap it when they come through the chute.
- You buy it. No yearly lease.
- Fits cows, yearlings and bulls. A lighter calf tag comes later.
One app for the fence and the herd
Draw pastures, see who's out, and keep chute-day records (vaccinations, breeding, treatments) in the same place. Made for folks who'd rather not fuss with passwords.
Chute-day records work with no signal and sign in with your phone number. The tag can also play a different call when you bring cake or mineral, and they learn to come to it like they come to the cake truck. Both are built in software and running on our test herd.

How we treat the animals
- No shock in the tag.
- The cue gets more urgent as she nears the line, up to a set limit.
- Once she's out, the tag goes quiet so she can come back.
- No cue when GPS isn't sure where she is.
- A vet fits the tags and can stop any trial.
- A real fence stays up the whole time.
What's coming
Run it by text, move when the grass is ready, and get a heads-up when a cow is in heat or off her feed. All built in software and running on our test herd.
