Your herd records, finally worth keeping

Right now they live in a notebook, on a whiteboard, or in your head. maiGrex puts them in one place that travels with the animal.

1

Snap.

Take a photo. Add a quick voice note if you want. Full screen viewfinder, gloves on, one hand, no menus to find.

2

Tie it to the ear tag.

Say the number or type it. maiGrex keeps the rest straight, including what happens when a tag gets replaced.

3

Done.

It saves right away, even with no bars, and syncs when you are back in range. The camera is up for the next animal.

About twenty to thirty seconds a head. Every entry builds a lifetime record you can pull up in seconds.

A documented animal is worth more at the sale

Buyers pay for what they can verify.

When you sell, the whole history goes with the animal. Photos over its life, weights, dates, what you noticed and when. It shows up in the buyer's account as a record that came from you.

The buyer does not have to take your word for it, and you do not have to take less for the animal because they cannot check.

It works where you work

Gloves on, no signal, sun in your eyes. It works anyway.

Works with no signal

Everything captures offline and uploads by itself when you get back in range. You can see exactly what is still waiting to sync.

Lifelong records

Every observation is kept, in order, for the life of the animal. Photos, notes, weights, breeding, and where it has been on the place.

Simple on purpose

If it is not fast, you will not use it. So we made it fast, and left out everything that would slow you down.

And when you get back to the house

Everything you captured out there is already waiting on the computer.

Look through the whole herd, pull up any animal's history, and handle your account from a real keyboard. Same records, more room to work.

Billing lives here too, not in the app. The app stores take a cut of anything sold inside an app, and that cut ends up in the price. Keeping it on the web keeps it out. See pricing.

Your data stays yours.

You own your records. We never sell them, and we do not share them for advertising.

What maiGrex does not do

maiGrex keeps your records. It does not diagnose animals.

It does not detect, diagnose, or treat any illness or condition, and nothing it shows you is veterinary advice. It stores what you write down and makes it easy to find later. Every decision about an animal is yours. Talk to your vet.

About Twisted Pine Cattle Co

We are not cattlemen. Ralph took over his family's ranch, and what nearly beat us was not the cattle, it was the records. Notebooks in the truck, photos buried in a phone, nothing you could hand a buyer.

Every tool we looked at wanted us to run the whole operation through it. We wanted one that got out of the way. So we built the tool we needed and left out everything we did not.

Based in Fort Worth, Texas. Read the rest.

Lock in half price for life.

Our first 100 Founding Herds get free use all through the beta, 50% off for life when we launch, and a founding number that is yours to keep. There are one hundred of them and there will never be more.
