What does the app do?

The INR log app is for people who are taking warfarin and their carers to keep track of their warfarin dose and INR results. Users are required to set their therapeutic INR range (upper and lower limit), select the tablets they use (brand and strength) and their test results (date done and INR result).

To help users identify the warfarin tablets they are taking, the app has images of the different brands (Marevan or Coumadin) and strengths. Users can set daily medication reminders and reminders for when their next test is due. The Resources section has provision to add or delete results and to add previous results. For the complete app description, go to the App Store or, for a more detailed review, see Reviews

PROS CONS 

✔ Simple and easy to use.

✔ Optional reminders to take warfarin and arrange blood tests on time.

✔ Displays blood results on a graph so trends can be monitored.

✔ Images of the tablets çan help patients/carers to take the right dose and be familiar with their warfarin tablets.

✔ Prepares a clear printable report to share results with nominated GP via email and to send to self and print.

✘ Selection of the Coumadin brand can be confusing – not all the strengths of Coumadin tablets in the app are available in New Zealand and the colours of the different strengths may differ to that used in New Zealand (there is a statement in the app reminding users about this, but it can be missed).

✘ Doesn’t provide additional patient information about warfarin (but the intention is for recording only and to see a healthcare professional if there are any concerns).

✘ The app selects the most appropriate daily dosing based on the overall weekly dose, which may be a different schedule to what people are used to taking.

✘ Available on iTunes for Apple devices only. Not available in the Play Store.
