HerdFlo

For small herds, homesteads & livestock keepers

Know what’s due.
Keep the record.

Keep breeding dates, treatment withdrawal dates and weights together, animal by animal. Spend less time hunting through notebooks when it’s time to check, treat or plan.

Calculate a due date

Your first 5 animals are free. No card required. Records need an internet connection.

Free livestock gestation calculator

Find a due date or work backward from one. Cattle breed presets adjust the estimate. Email required on first use; after setup, the calculator works offline.

Advanced: custom gestation length

Before you start

What can I try before paying?

Create a free account and keep records for up to 5 animals. Add a breeding, treatment or weight to see how the herd book fits your day. Choose Pro when you want its calendar, email alerts, growth reports, CSV exports or more animals.

Does it work without a signal?

The calculator works offline after your first online setup. Saving and viewing herd records, signing in and billing need an internet connection.

Will it replace veterinary advice?

No. Due dates are estimates, growth projections follow your recorded weights, and withdrawal dates depend on the information you enter. Follow your veterinarian’s instructions and the product label.

How do I get help or cancel?

Email support@farmsflo.com for help. Web subscribers can use Manage billing in My Herd; app-store subscriptions are managed through the store where you bought them. Canceling stops future renewals; paid access lasts through the paid period.
