About this app

INR Diary assists in following up your anticoagulation programme. Insert the daily dose of your blood thinner medication (Warfarin, Coumadin, Marcoumar, Sintrom, Marevan, Falithrom, ...) for a certain period of time. You can add one dose at a time or multiple doses in bulk, according to a dose scheme. Doses can be expressed as an amount of pills or in milligrams. The app will remind you to take your daily dose at a personally configurable time.

Tap on your daily dose to confirm you've taken the blood thinner medication. The timestamp of confirmation is stored in the app. That way, you'll never forget if and at what time you've taken your medication.

The app can also record the INR measurements of your blood and visualizes the evolution of your INR in time. The app also reminds you when a new INR measurement is planned.

Dose and INR data can be exported or imported for backup purposes, or if you want to discuss this with your medical expert.

I've used this app for several years. It's been an invaluable tool in keeping track of my INR for my doctor. I REALLY appreciate the quick response from the developer when there is an issue. I HIGHLY recommend this app for INR tracking.

Hello Jeff. Please check out the latest version 2.3.3 of the app. There was indeed a problem with data export which is now resolved. Thank you for updating your review score if all is well now :-) Greetings.

Hi Mark. I have sent you a reply on July 8 with instructions how to change the dosage scheme. This should resolve the problem. Can you please reconsider your score? Thanks!

Great basic app, solid support, does exactly what I need it to. I wish it had a check box or the like that could be used for a daily marker of alcohol consumption, high vitamin K foods, etc. Either way, love the app.
