For owners, by an owner.

Keeping a horse means keeping records. What the vet said, when the farrier came, which wormer and when, what the jab dates are, what it all cost. For most people that lives in five places at once: a phone calendar, a group chat, a drawer, a spreadsheet, and the bit you meant to write down and did not.

None of those places knows about the others. Nothing owns the horse.

This does. One record per horse, with the dates worked out from what is in it rather than from a list you have to maintain, and quick enough to use at the yard with cold hands.

Free to use. No card, no catch.

It is free because charging owners for the ability to keep the records the law already asks them to keep is not a business we want.

There is no advertising. A record book that shows you adverts based on your horse being lame is not a record book.

• Sell your data, rent it, or train anything on it.
• Show you advertising.
• Name a veterinary medicine anywhere the public could see it, because advertising a prescription medicine is an offence.
• Guess at a legal deadline. Every rule cites the page it came from and the date somebody read it, and where nobody has read it the tool declines to answer rather than inventing a number.
• Pretend to be a passport, or produce anything that could be mistaken for one.
• Hold your records hostage. Download my record, in Settings, gives you a copy whenever you like, and it is offered again before you delete your account.

The record book is live on the website: the horses, the jabs, the worming, the farrier, rides, feed, costs, the tack room and the yard. The app for iPhone and iPad, which works at a yard with no signal, is being tested.

Three of the free tools answer, each from a source it names with the month somebody read it. The flu jab checker refuses to answer, because its rules have not been checked against a governing body's rule book, and a tool that guesses is worse than no tool.

The pictures on the home page are the real screens, made from the example yard.
