A mare owner app for the whole breeding year
From the first heat you chart to the foal standing in the stall, breeding a mare is a year of dates worth keeping straight. HorseBook follows your mare through every step — on your phone at the barn and on the web when you sit down to plan.
No card to start. Works on iPhone and any web browser. Plans from $4.99/mo.

Chart heat cycles and log the breeding
Track your mare through her cycle so you know when she is ready, then record the breeding — the date, the method, and the stallion — right where you will look for it next year.
- Heat cycle tracking so you can time the breeding
- Breeding records with cover date and method
- Notes and photos kept with each cycle
- One clean season history per mare

Keep every pregnancy check in one place
Log each ultrasound and check across the roughly eleven months of gestation, so you always know where your mare stands and what the vet found last time.
- Pregnancy checks logged over the gestation
- Photos from each ultrasound kept with the record
- A running pregnancy status you can see at a glance
- Due-date awareness as foaling gets close
From foaling night to a progeny record
When the foal hits the ground, record the foaling and turn it into a progeny record tied back to the sire and dam — so the foal starts life with its own file.
- Foaling records for the big night
- Progeny records linked to sire and dam
- A new horse profile for the foal when you are ready
- The whole cross, from breeding to foal, in one line

Vaccines, Coggins, and the rest of the paperwork
A broodmare still needs her spring shots, a current Coggins to travel, and a farrier on schedule. HorseBook keeps all of it beside her breeding record, and the AI scanner files the paper for you.
- Medical records — vaccines, Coggins, vet visits — per mare
- Snap a Coggins or vet paper and the scanner files it
- Calendar reminders for shots, farrier, and appointments
- Expenses tracked by horse so you know what she costs

Frequently asked questions
What can I track for my mare in HorseBook?
Heat cycles, breeding records, pregnancy checks, foaling, and progeny — plus everyday health records like vaccines and Coggins, a calendar with reminders, and expenses. Everything for one mare lives in one profile, and it syncs between the iPhone app and the web.
Do I have to be a big breeding operation to use it?
No. HorseBook works just as well for one mare as for a barn full. The Hobby plan covers up to 3 horses for $4.99/month, which is plenty for a single mare and her foal, and Pro removes the limit when your program grows.
Is there an Android app?
There is a native iPhone app and a full web app. The web app runs in any browser, including on an Android phone, so you can use HorseBook on Android — there just is not a separate app in the Play Store.
Can I keep the foal and mare records linked?
Yes. Foaling creates a progeny record tied back to the sire and dam, and you can spin the foal up into its own horse profile. The connection between mare and foal stays in the record.
What does it cost?
A 14-day free trial with no card required. After that, Hobby is $4.99/month for up to 3 horses and Pro is $9.99/month (or $99.99/year) for unlimited horses and 200 AI document scans a month.
