What does the app do?

INR Tracker in a web-based, online tool for people taking warfarin to track their INR, medication and appointments. It includes a food database so users can record their daily foods and drinks to find out how much vitamin K they are consuming. The app also has provision for recording other information such as weight, blood pressure, wellness, exercise, menstruation and temperature. Users can generate reports of their warfarin dose and INR results.

While this app has many useful features, an area of concern is the discussion forum that is not monitored by a health professional.


✔ Can keep track of INR and warfarin doses/missed doses, activity and check which foods are high in vitamin K.

✘  US-based so some things might not be relevant or easy to convert to NZ lifestyles.

✘ The discussion board is not monitored by a health professional.

Comments: This web-based, mobile-friendly tool enables patients to log their daily activity, analyse their INR results, have access to articles, use a Vitamin K food database, DVT and PE calculators and join a discussion forum. Can log appointments, blood pressure, wellness and exercise. Available in English, Spanish, German and French. Overall it is a very well designed app and would be very helpful for people wanting to tract their warfarin dose, INR results and other health data. It has comprehensive information about vitamin K but since this is US-based, some of the foods may not available in other countries. It has an active discussion board but this is not monitored by a health professional.
Safety concerns: There is a fairly active discussion board that is answered by other patients/members of the public. Responses are not monitored by health professionals so the advice may not be in line with medical recommendations or be evidence-based.
New Zealand relevance: The foods listed in the vitamin K food database are US-based foods with brands not available in NZ.
