Story behind the app
In September 2014, my wife, who was 30 years old at the time, underwent surgery to replace her biological cardiac valve with a mechanical one because it was wearing out. Consequently, she had to start taking blood thinners daily. The daily dose often varies from day to day. She also sometimes doubts whether she has taken her medication. This is, of course, very dangerous.
Around the same time, I was looking for an interesting case study for my first Android app. Using my wife as a guinea pig, I created a first version. INR Diary was born!
Today, INR Diary is the highest-rated INR management app for Android and iOS. It is available in seven languages: English, German, Spanish, Catalan, French, Italian and Dutch. It is currently used by over 10,000 patients taking blood thinners in more than 40 countries worldwide.
At the end of 2020, the app underwent a complete overhaul and became available on iOS too.
