BredDay: Gestation Calculator
Livestock breeding & due dates
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Free to use: due dates for 8 species and a herd of up to 3 animals, with checkpoints, reminders and calendar — no subscription. No ads, ever. Works with no signal.
Breeding date in, due date out. BredDay is the livestock gestation and breeding calculator built for the barn — no ads, no accounts, and it works with no signal.
Enter a breeding date and species, and BredDay computes the estimated due date, builds a checkpoint schedule, and counts it down on your home screen. Everything runs fully offline; your herd data never leaves your phone.
FREE TO USE
Quick Calc for all eight species and a herd of up to 3 animals — with built-in checkpoints, reminders, calendar and history — need no subscription. BredDay Pro unlocks unlimited animals, custom checkpoints and farm routines, CSV export and the home-screen widget.
EIGHT SPECIES
Cattle, horses, goats, sheep, pigs, rabbits, alpacas, and llamas — with breed-specific gestation adjustments and a per-animal override, because you know your stock.
YOUR HERD, SORTED
Log every animal and see who's closest to due at a glance, color-coded by how soon. Track breeding history and outcomes (live and lost), and revise a past record if you mislog it.
NEVER MISS A CHECKPOINT
Vet-informed checkpoint templates for every breeding — vaccination windows, dry-off, pen prep, watch-closely — plus your own custom checkpoints to match your farm's routine, each with an optional local reminder.
QUICK CALC
Need a fast answer at the chute? Pick a species and a date and get the estimated due date instantly — nothing to save.
CALENDAR & WIDGET
See every breeding day, checkpoint and due date on a month calendar with an Upcoming list of what comes next, and keep a countdown right on your home screen ("Bessie · 14d").
PRIVATE BY DESIGN
No ads. No analytics. No tracking. No account to create. Export your herd to CSV whenever you want your data elsewhere.

Ratings & Reviews
• Upcoming: the Calendar now lists your herd’s next dates — breedings, checkpoints and due dates — so the week ahead is visible at a glance. Tap any row to open the animal.
• Appearance: choose System, Light or Dark in Settings — light for a bright barn, dark for the evening.
• Add an animal before it is bred: switch off “Currently bred” and it starts open; log the breeding from its page when it happens.
• Fixed a stray “Notifications Disabled” alert when only past breedings were on file.
