Pregnancy checks & reproduction tracking
HerdHawk is the chute-side recorder for ranchers, vets and preg-check techs. Results save on the phone the moment you tap, sync when you're back in range, and turn into calving dates, reports and Excel-ready spreadsheets.
Results scribbled at the chute get copied into a spreadsheet at night, if the page survives the day. HerdHawk saves each result the moment it's tapped.
Most apps stall without a connection. HerdHawk is offline-first: it records on the phone and syncs record by record when the signal comes back.
Herd-record apps commonly run $13 to $18 a month. HerdHawk is $2.99 once. No subscription, no ads, no upsell screens.
Everything in the box
Every figure comes from your own records. Where the records don't support a number, HerdHawk shows a dash instead of guessing.
A full-screen, high-contrast recorder built for gloves and glare. Pick the tag color, punch the tag on a big keypad, tap the result. HerdHawk identifies the animal before it saves, blocks double taps, and gives you Undo.
Every result is saved on the device first and queued. It never waits on the network, and a dropped connection never loses an entry.
Animal profiles with a full timeline: heats, AI and natural service, bull exposure, checks, calvings and losses. Corrections keep the original, so history is never overwritten.
Group a season's breeding: enroll females, record bulls, turnout and removal dates, and see each cycle's outcomes, check history and calving window. Compare cycles year over year.
A calving view of who's due, who's overdue and who has calved, worked out from your checks and breeding records. Record a calving in a few taps: the calf joins the herd with its dam, sex and birth weight.
Treatments, vaccinations and other health entries for one animal or a whole group. Withdrawal dates are kept as you enter them from the label, and follow-ups show up on the dashboard and calendar.
A "Needs attention" list up top: overdue rechecks and reminders, calvings and follow-ups due soon, changes waiting to sync. Below it, your herd's numbers, each opening the list behind it.
Expected calvings and heats, recheck dates, check sessions and reminders, in a month grid or list. Each entry says whether it's recorded, estimated or scheduled.
Pregnancy outcomes by age group, tag color and herd; check sessions; cycle comparisons; calving schedules; animal and health histories; finance summaries. Each PDF carries the ranch, the filters, the date and page numbers.
Reminders every few days, weeks, months or years. The Android app puts reminders, health follow-ups, rechecks and calvings due in your notifications at the time you choose; the web app shows what's due today.
Your pastures with acres, water and fence notes. Move herds between them and see where each herd is and how many days each pasture has been grazed this year.
Find any animal from any screen by tag, electronic ID, name or other ID. A Bluetooth reader in keyboard mode types the EID straight into search or Chute Mode.
Charts from your own records: herd size over time, animals joined and left, pregnancy rate by cycle, calvings by month and how spread out they are. Income and expenses by category, for each herd or the whole ranch, with per-head figures where you record a head count.
Dark leather for the barn and evenings, a light Daylight theme for reading outdoors, or follow the phone. Chute Mode keeps its own Low-light and Sunlight themes.
Export animals, sessions, results, cycles, reproductive and health history, finances and pasture moves. Tags keep their leading zeros, dates stay dates, and the export screen tells you exactly what's included: "212 of 212 will be exported."

Invite your crew and vet with a link or a code, sent however you like, with the role they'll have. Roles are enforced on the server, not just hidden in the app. Two phones can record the same day; edits to different fields merge, and true conflicts wait for your review.
Set up the tag colors your ranch actually uses and, if you like, map a color to an age group. Tags are stored exactly as written, so Yellow 12 and Red 12 are different cows and 012 stays 012. Gestation length, heat cycle and recheck interval are yours to set, per breed if needed.

How it works
Create a free account, name your ranch, and pick your tag colors, age groups and gestation defaults (283 days unless you say otherwise).
Add your herd, or skip it: unknown tags are added at the chute. Enroll females in a cycle and record AI dates or bull turnout.
Start a session with date, herd, cycle, examiner and method (ultrasound, palpation, blood test). Tag, tap, next. Signal or not.
The dashboard, calendar and reports fill in from your results: expected calvings, open cows, rechecks due. Print it, save a PDF or export to CSV.
Offline-first, for real
HerdHawk was designed from day one to save on the phone first. When you're back in range it syncs one record at a time, and it only says "All changes synced" when the sync has actually finished.
Dashboard, calendar & reports
On a laptop at the kitchen table or the vet clinic, the same records lay out wide. Pregnancy rates always say how many were checked, so a half-finished day never looks like a great season.
Pregnant 89% · 169 of 196 checked
Sample screen with a fictional ranch and fictional figures.
Pregnant % leaves out rechecks and unchecked cows, and every report says "17 of 24 checked" so the number can't mislead.
Recorded, confirmed, estimated and scheduled are always marked. No date is invented when the records don't support one.
Pick a breeding cycle and herd once; the dashboard, reports and exports all follow, and say which filters are applied.
Free tool
A taste of the math HerdHawk does for every cow. Enter a breeding date, or a bull turnout and removal date, and get the expected calving date or window.
In the app, the estimate uses the best record available: the due date from the check, fetal age at the check, the one breeding that fits, or your breeding window. Gestation follows the cycle, then the breed, then your ranch default.
Who it's for
Know which cows are bred, which are open and when calves are due. Cull and marketing calls start from facts, not a smudged notebook.
Record by examiner and method, add days bred, and hand over a session report on paper, as a PDF or as CSV the same afternoon.
A big keypad, one-tap results and live counts mean the phone never slows the line. Undo fixes a mis-tap in a second.
Pricing
No monthly plan, no per-head fees, no ads. Every feature on this page is included.

Questions
Yes. You pay $2.99 once on Google Play. There's no subscription, no per-head charge, no ads and nothing to buy inside the app. The web app is free with your HerdHawk account.
Yes. Once you've signed in on the phone, you can record animals, breeding records, check sessions and results with no signal. Everything saves on the phone and syncs when you're back in range.
The very first sign-in, creating a ranch, and the first download of your ranch's records need a connection.
HerdHawk is built for crews. An owner invites people with a link or a code (send it by text, email or the phone's share sheet), choosing their role: manager, worker or viewer. Each person signs in with their own account. Two phones can record the same day; changes to different fields merge, and if two people change the same thing you choose which to keep.
Yes, with Bluetooth readers that work in keyboard mode (they type the tag number as if on a keyboard). Scan into search or Chute Mode and HerdHawk finds the animal by its electronic ID. Readers that only connect over a serial link aren't supported yet.
Yes. Add reminders, one-off or repeating every few days, weeks, months or years. The Android app puts reminders, health follow-ups, rechecks and calvings due in your phone's notifications at the time you choose; they're made on the phone, with nothing sent from a server. The web app shows what's due today when you open it.
Yes. Record treatments, vaccinations and other health entries for one animal or a group, with the product, dose, withdrawal date and a follow-up. Withdrawal dates are kept exactly as you enter them from the label; HerdHawk doesn't look up products or check doses, and it isn't veterinary advice.
The app is on Android. On an iPhone, iPad or computer, use the HerdHawk web app in your browser with the same account. Open it once while connected and it keeps working offline after that.
HerdHawk uses the best record it has: a due date given at the check, fetal age at the check, the only breeding that fits, or the breeding window. It adds gestation from the cycle, the breed or your ranch default (283 days). Estimates are always labelled, and if there's nothing to go on, HerdHawk says so instead of guessing.
Yes. Export animals, check sessions, results, breeding cycles, reproductive and health history, finances and pasture moves as CSV files that open cleanly in Excel. Tags keep leading zeros, and the export tells you how many records match your filters before you download. Reports can also be saved as PDF.
Hit Undo, or tap the entry to change it. A double tap of the same result is ignored. When a result is changed, the new one counts and the original stays in the animal's history.
Only people who belong to your ranch, with the access their role allows. That rule is enforced on the server. See the privacy policy for the details.
In the app, open Settings, then Ranch and account, then "Delete my account", or email support@herdhawk.com from the address on the account. What is deleted and what stays.
One-tap results, no signal needed, calving dates by supper. All for less than a cup of coffee at the sale barn.
