About this app

INR Diary has already helped more than 10,000 patients to correctly monitor their anticoagulant treatment.

Enter the daily dose of your blood thinner for a specific period. You can add doses day by day or according to a repeating dosing schedule.

All VKAs (vitamin K antagonists) are supported: Warfarin, Coumadin, Jantoven, Marevan, Marcoumar, Sintrom, Mini-Sintrom, Sintrom Mitis, Falithrom, Phenpro, Préviscan, Aldocumar, etc. Depending on the type of blood thinner, doses are entered in number of tablets/pills or in milligrams.

Never forget to take your anticoagulant medication again! The app reminds you of your dose every day at a time you set yourself. Click on your daily dose to confirm that you have taken it. The time of each confirmation is stored in the app.

View the evolution of your INR. The app allows you to enter your INR measurements and presents a graphical overview where you can follow the evolution of your doses and INR over time. If desired, add a comment to any measurements that deviate from your therapeutic range, for example if you have eaten too much vitamin K or were ill. The app also reminds you of your next injection date.

Effortlessly share doses and INR measurements with your Anticoagulation Clinic (INR Clinic, Coumadin Clinic, Warfarin Clinic) or therapist via a customizable and clear PDF report. Easily import your existing archive of doses and INR measurements into the app. Export data as a backup or to transfer it to another device.

A good app that does exactly what you need. my only issues are the swipe to delete needs to be removed/changed, the amount of times I've accidentally deleted my doses and had to re-enter them is annoying. also the reminder to take your dose doesn't work.

Love this app, using it since November 2023 and so far I never encountered problems with it. But lately the notifications don't work anymore. All the settings are enabled, time is set right. Phone (Fairphone 4) has been restarted but still it doesn't work. Not the end of the world but it would be nice if it did work again though. Thanks in advance

"Simply the best!" Hi there, Just a small advice, canceling confirmation of a dose should bena little bit harder. For e.g. long pressing instead of tapping. The devices with no back button can interfere with the interface while doing a "back" action. While the "back" operation, mu finger can also undo the current dose's confirmation. Thanks.
