Story behind the app
In September 2014, my 30-year-old wife received a mechanical cardiac valve because hers was wearing out. She needed to start taking blood thinner medication daily, at a fixed time. The dose often varied from day to day, which made it difficult to track. Sometimes she doubted whether she had taken the anticoagulent. It even occurred that she'd forget to take it, which can of course be very dangerous.
In the meantime, I was looking for an interesting case for my first Android app. With my wife as a guinea pig, a first version was created. INR Diary was born!
Today, INR Diary is the best rated INR management app for Android. It is available in 6 languages: English, German, Spanish, French, Italian and Dutch. INR Diary has been downloaded over 1000 times in over 30 countries throughout the world.
