BredDay: Gestation Calculator

Breeding date in, due date out — for cattle, horses, goats, sheep, pigs, rabbits, alpacas & llamas. No ads. Works with no signal in the barn.

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.

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 due date and checkpoint on a month calendar, 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.
