Our approach
We didn't want to build something bloated or ugly, or make you phone someone to find out the price.
No commitment
Billing is monthly, and if you cancel you're done at the end of that month. There's no notice period and no exit fee.
A simple application
6 screens is the whole thing. Most people record their first INR without being shown how, and that was roughly the bar we set ourselves.
Clearly posted prices
Every rate is published and keyed to how many patients you follow, so a pharmacy with 6 doesn't pay what one with 80 pays. There's no quote to request and nothing to negotiate.
INR Management for Pharmacies, Labs & Clinics
Anticoagulation follow-up without the spreadsheet: record an INR, get the dosing calendar, print the prescription, book the next visit. Free for 1 or 2 patients.
Up to 2 patients, upgrade anytime.
Before you sign up
What most people check first.
Built for teams
Add colleagues with view or edit access from the team page. The bill follows your patient count, so it doesn't move when you add someone.
Priced on the work at hand
You pay for the number of patients you follow. It's free at 1 or 2, and it stops at $99, which covers you to 125.
Your data stays yours
Export the whole account to CSV from your account page, whenever you want and without asking us. What comes out opens in any spreadsheet.
Decide where your data lives
Keep patient records on our servers, backed up and open to your colleagues — or entirely on one computer of your own.
Adapt the clinical protocol
You set the dose ceilings, the INR thresholds, and how much a dose may change in a week. Retroact holds the line you draw and flags anything past it. It never proposes a dose.
Try it before you talk to us
The demo on the Retroact page is the real application, running on sample patients. Look at it before you talk to anyone — or skip that and go straight to starting free.
