Herdline
The milk register says what each cow gave. The wall calendar says when she was served. Herdline keeps both in one place, so they finally agree — and works out the two numbers that decide whether a dairy makes money: cost per litre and calving interval.

Who it is for
Owner-operators running five to sixty cows
Usually one or two sheds, often rural, often with patchy data. A missed heat costs a full twenty-one-day cycle and real money. A forgotten milk withdrawal after treatment risks a rejected consignment. Both are bookkeeping problems, and both are solved by a record book that computes rather than one that just stores.
Features
What Herdline does
Animal register
Tag, name, breed, sex, date of birth, dam and sire, shed and status — heifer, milking, dry, pregnant, sold or culled.
Twice-daily milk recording
Morning, midday and evening. The whole parlour in one pass, with a running total as you enter it.
Reproduction cycle
Heat, service, pregnancy check, calving and dry-off. From a service Herdline derives the check date, the expected calving 283 days on, and the dry-off date.
Today / Upcoming board
Every dated obligation in one list — heat checks, pregnancy checks, calvings, dry-off, vaccinations and withdrawal windows. In-app only: Herdline sends no push notifications.
Lactation records
Lactation number, days in milk, 305-day and total yield, peak yield and the day it fell on, plus a per-cow lactation curve.
Feed & milk ledger
Feed purchases and milk sales become a running margin and a cost-per-litre figure. A record book only — Herdline moves no money and connects to no bank.
Health & withdrawal log
Vaccinations, deworming and treatments, each with the milk withdrawal date your vet set. Herdline records; it gives no veterinary advice, dosage or protocol.
Insights & charts
Herd yield over 7, 30 or 90 days, top and bottom producers, feed cost against milk value, and the cost-per-litre trend — all computed on the device.
Search, filter and tags
Full-text search across cows, treatments, ledger entries and reproduction events. Filter by status, breed or shed; pin the cows you watch.
Streaks, goals and milestones
A recording streak that means something, targets for daily yield, cost per litre and calving interval, and milestones that unlock from real husbandry.
Export, import and backup
Full JSON backups you can restore from, CSV for every entity, and the share sheet to send a backup wherever you keep it.
Archive, undo and theming
Sold and culled cows archive with their history intact, every change offers undo, and theme, accent and density are yours to set.
Permissions & privacy
One permission, and here is why
INTERNET
Requested for exactly one purpose: opening this site's privacy policy inside the app's Settings screen. No other network use, no analytics, no advertising, no third-party SDK.
Nothing else
No camera, no location, no contacts, no storage permission, no notifications. Herd records are stored encrypted on the device and are never transmitted.
Important
Herdline is a record book, not veterinary advice
The application suggests no treatment, no dosage and no withdrawal period, and makes no diagnosis. Withdrawal dates are the ones your own veterinarian gave you, entered by you. Always follow your veterinarian and your local milk-safety rules.
