Sire Record

A vet or livestock technician running artificial insemination services
across a village's herds ends up holding two things in memory that really
shouldn't live there: which animal is due when, and whether their own
work is actually landing. A farmer asks when to expect a calf and gets a
rough guess; a technician asked how good their results are has no real
figure to give, just an impression.

Sire Record replaces both guesses with a real record. Log a service
against an animal, and it draws as a thin track running from the service
date toward an expected-calving window projected from the breed's own
typical gestation length - never a single false-precise day, always a
range, with today marked on it so a glance shows whether a pending
service is still approaching its window, sitting inside it, or overdue
without a recorded outcome. A separate view reads back each technician's
own confirmed success rate, counted only from services that were actually
followed up - a service nobody checked on helps or hurts nobody's figure,
and a rate only appears once there's genuinely enough of a resolved
record behind it to mean something.

This app gives no veterinary or breeding advice, and guarantees no
outcome for any specific animal: a calving window is typical for the
breed, and a success rate is a technician's own past record, neither a
promise. It also holds no money anywhere in it - no service fees, no
charges, no rates of any kind.

Everything stays on the phone it's used on. There is no account, no
sign-in, and no data of any kind sent anywhere.
