Built for the work

A purpose-built tool, not
a calendar with notes.

Built for the people who read the numbers — vets in practice and breeders in the kennel. Every reading lands on a calibrated trajectory, with the stage and the next move named clearly.

Calibrated readings
Log values in ng/mL or nmol/L, with built-in miniVIDAS-to-IDEXX conversion. Each reading is classified by stage — anestrus through to a closed window — and plotted on the trajectory curve.
The mating window
Ovulation is detected from 6 ng/mL. Progestro opens the mating window, estimates the optimal breeding days, and alerts your handler — whether you're breeding naturally or with frozen semen.
A kennel or a caseload
Track every female in your program — or every patient on your books — side-by-side. Quick check a one-off reading without opening a cycle.
The reading

The clearest curve
you've ever read.

Every dot is a measurement. The band marks the mating window. The rose dot is where she is right now. Stop translating tables in your head — just see the stage.

Proestrus · Rising toward ovulation, 1–5 ng/mL.
Ovulation · Detected at 6–10 ng/mL. Window opening.
Mating window · Breed within 2–4 days of ovulation.

How it works

Three steps. Then breed
with the right day on your side.

STEP 01
Add your dogs
Name, breed, birthday. Progestro keeps a profile for every female in your program — start a new cycle whenever she comes into season.

STEP 02
Log each reading
Enter the value from your assay — ng/mL, nmol/L, or miniVIDAS. Progestro classifies the stage, updates the trajectory, and tells you when to test next.

STEP 03
See the moment
Ovulation detected — the mating window opens. Progestro calculates the optimal breeding days and alerts your handler. You'll know to within 24 hours.
OPTIMAL WINDOW

Progesterone timing shouldn't come down to a gut feeling. One clean curve per dog, the optimal window called out, the next test scheduled — so you act on the number, not a hunch.

Questions

The short list.

When does Progestro launch?
Very soon — we're in the final review with the App Store and Google Play. Join the waitlist above and we'll email you the day it goes live, with the download links.
Does Progestro replace my vet?
No. Your vet runs the assay — Progestro is where the number lives after. We turn a column of values into a clear trajectory and call out the optimal window so you can act on it.
What units does it support?
Both ng/mL and nmol/L. Set your preference once in your profile and every reading is shown in your unit. If you're using a miniVIDAS machine, Progestro converts your readings to IDEXX-calibrated values automatically — no manual table lookup needed.
How accurate is the stage classification?
Stages use the canonical canine progesterone bands. Progestro doesn't guess — it places her reading on a published curve and shows you exactly where she sits.
Can my handler see her cycle too?
Yes. Each cycle has a shareable read-only view — handler, stud owner, or co-breeder can follow the trajectory and get the optimal-window alert.
What does it cost?
$14.99/month billed monthly, or ~$12.50/month when you pay yearly — that's $149.99/year and saves you two months. Every feature is included on both plans. Starts with a 7-day free trial. Prices shown in USD; your local price appears at checkout.
