Mare Foaling Tracker: Estrus
Gestation & Heat Cycle Planner
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Breeding a mare? Log daily teasing scores, see today's cycle phase and breeding window, and track gestation with milestone windows for every mare. Per-mare, per-cycle.
Breeding a mare means tracking two clocks that move on their own every single day. Mare Foaling Tracker keeps both in one place, per mare, so nothing slips through.
During breeding season you tease your mare and score her daily, but a high score alone does not mean she is ready. Ovulation happens before the end of estrus, so a rising score often means wait, not go. In early spring, a long heat can be a transitional cycle with no ovulation at all, and breeding then is wasted. After breeding, a second clock starts, with time-sensitive windows for twin checks, heartbeat checks, and vaccine timing. Keeping all of this in a spreadsheet is how details get lost.
HOW IT WORKS
1. Add your mare and log her daily teasing score, or enter her breeding date.
2. The app reads elapsed days against general equine averages and her own history.
3. You get today's cycle phase, an estrus and breeding window estimate, a gestation countdown, and milestone windows that open and close as days pass.
It takes 20 seconds to set up. No account required.

Today's Cycle Phase
Log a daily teasing score and see a plain-language phase for your mare, approaching, breeding window, transitional heat, or diestrus, with the reason behind it.
Breeding Window Estimate
An estimated ovulation and breeding window based on her cycle and your breeding method, so you can plan natural cover or insemination timing.
Gestation Countdown
Enter a breeding date and see days in foal and the estimated due window, based on general equine averages.
