What BredDay does
New
Everything you need from breeding to birth
One tidy app for the whole cycle — figure the due date, keep the herd, and never miss a checkpoint, all without a signal.
🐮
Your whole herd, in order
Log every animal, track breeding history and outcomes (live & lost), and see who's closest to due at a glance — sorted and color-coded by how soon.
✅
Checkpoints & reminders
Vet-informed checkpoint templates for every species — plus your own custom checkpoints to match how your farm actually runs, each with an optional local reminder.
🗓️
Calendar view
Every due date and checkpoint laid out on a month calendar, so nothing sneaks up on you mid-season.
📲
Home-screen widget
A countdown right on your home screen — “Bessie · 14d” — and the next three coming up. Glance, don't dig.
⚡
Quick Calc
Need a fast answer at the chute? Pick a species and a date — due date on the spot, nothing to save.
🔒
Private by design — and it works in the barn
100% offline: no signal, no problem, and no account to create. No ads, no analytics, no tracking — your herd data never leaves your phone (the App Store label reads Data Not Collected). Export the whole herd to CSV any time it needs to go elsewhere.

Averages drawn from published university-extension gestation tables, with breed adjustments built in. Every herd is different — override the length on any animal. Checkpoint templates describe common practice, not veterinary advice; confirm timing with your vet.
No ads. No accounts. Works with no signal in the barn.
That's the whole promise.
