If you take Warfarin or Coumadin, INR log can help you to keep track of your treatment.

It is easy to use and allows you to record all your INR results and your treatment prescribed by your doctor. Each day it will show you your warfarin dose and sends you an alert when your treatment is due. It will also remind you when to take your next INR test to help you achieve the best possible control.

It is very flexible and allows you to enter your own treatment range and select up to 3 different size tablets. You can record your dose as a daily dose or weekly dose and change the dose very easily based on your doctor's advice.

Your INR results are displayed graphically and in a table and you can add earlier INR results so you can see a complete record over time.

You can keep track of how well your treatment is going by following your time within the therapeutic range. This is a good measure of anticoagulant control and ideally should be above 60%. You can also keep track of your drug adherence if you record your treatment every day.

INR log is ideal for anybody taking warfarin, whether you are self-testing using a near patient testing device or if you are managed through an anticoagulant clinic or hospital laboratory.

INR log has been developed by a Consultant Haematologist with more than 25yrs of experience managing people on warfarin. It has been designed to be easy to use providing you with the important information you need to achieve safe control.

Please note:

INR log does not provide any medical advice about warfarin treatment. INR log is designed to be used only in conjunction with support from your healthcare professionals. It is designed as a convenient means of recording your treatment. If you have questions regarding your treatment you should consult your doctor supervising your treatment.

Great app that I’ve been using since INR ONLINE finished.
After recent iphone update I can no longer open the app.
I am worried that by deleting and re- installing the app I will lose all my INR history.
