Warfarin & INR tracking, made simple.

INR Mate helps you record INR results, log warfarin doses, set reminders, review trends and keep appointment-ready records across iPhone, iPad and Apple Watch.

Why I built it

For tracking and record keeping only. INR Mate does not provide medical advice or dosing recommendations.

Built from lived experience

Why I built INR Mate.

I’m Alistair Hutchinson, a UK-based Nurse Practitioner with over 25 years of healthcare experience, and I take warfarin long term after an aortic valve replacement.

I built INR Mate because I wanted a calmer, clearer way to keep my INR results, warfarin doses, reminders and notes organised, without pretending an app should replace clinical advice.
