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.

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.

Reviewer: Angela Lambie, Pharmacist, Auckland

Comments: This app is a simple way to keep track of your INR results and warfarin dose. It has optional reminders to take warfarin tablets and to have an INR blood test. INR results are displayed in a graph which is useful to check if they are within the target range and to monitor trends over time. Results can be prepared into a printable report to email to self or nominated GP. Overall this is a very simple and clear tool to help people to take their warfarin at the right dose and on time.
Safety concerns: None, but relies on data being correctly entered.
New Zealand relevance: Relevant to New Zealand users – the app was developed in New Zealand. Marevan is the most commonly used brand of warfarin in New Zealand. Not all the strengths of Coumadin tablets in the app are available in New Zealand. There is a caution reminding users to be careful when selecting their tablets – different colours are used in different countries.
