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.

Frequently asked questions

Can I transfer data from the old Android version of the app?

The initial version of INR Diary is no longer maintained. But if you still own a copy of that app, it is possible to transfer all your data to the new version of INR Diary. Perform the following steps:

  1. In the old app, use the Export function from the Settings screen. This results in 2 export files being stored on the filesystem of your Android device: doses-yyyymmdd.inr and inrs-yyyymmdd.inr.
  2. Use Android File Transfer to copy over these files to your PC or laptop. Usually, these files are in the "/sdcard/0/INR Diary" or "/mnt/sdcard/0/INR Diary" folder of your Android phone.
  3. Important! Rename the file extension for both files from .inr to .csv. You should now have 2 files on your local system: doses-yyyymmdd.csv and inrs-yyyymmdd.csv.
  4. Finally, use the Import function in the new app to import the dose export into the doses overview and the INR export into the INR overview.

Please contact us should you run into any problems transferring data.

I cannot freely enter a dose value

The app works with 2 types of dosing: pills based dosing and milligram based dosing. This dosing type depends on the type of medication that was configured the first time you opened the app.

  • Milligram based dosing is used for users of Warfarin and Acenocoumarol (Coumadin, Marevan, Jantoven, Sintrom). With this dosing type, you can enter the exact decimal dose (in mg) that you need, with no upper limit.
  • Pills based dosing is used for Phenprocoumon patients (Marcoumar, Falithrom). Using a dropdown, you can select full, half or quarter pills as a dose, for doses up to 3 pills.

You can change the medication type in the Settings page of the app. If you use a medication that is not in the list, simple select "Other" and choose between milligram based or pills based dosing.

How do I delete a dose?

You can delete a dose either from the doses overview or from the dose scheme by either:

  • Swiping a dose value right to left. Please check out the this instruction video to see a demo.
  • Tapping and holding the value you want to delete and selecting "Delete" from the popup menu.

The daily dose reminder arrives late or not at all

If you have configured a daily dose reminder in the app but you don't receive any notification, or you do receive a notification but much later than the configured notification time, please run through the following steps:

  1. Make sure that notifications are enabled in the app. Verify that this is the case in the Settings screen of the app. Also make sure that the notification time is set correctly (e.g. AM vs. PM).
  2. You only get a reminder if an unconfirmed dose is configured for today. So verify that you a dose is indeed present for the day on which you expect to receive a notification.
  3. If that is the case, make sure that your Android or iPhone allows notifications for your app.
    On Android, go to "Settings" and search for "INR Diary". Then click on "Notifications" and verify that notifications are allowed.
    On iOS, go to "Settings" and search for "INR Diary" at the bottom. In the settings of the app, click on "Push notifications" and enable the notifications for the app with the sliders.

Should notifications still not work for you, please contact us to help you solve the problem. Remember to include your phone and iOS/Android version.

How can I report data to my therapist?

The latest version of INR Diary includes a PDF report functionality. The generated PDF can be printed or shared with your therapist, e.g. by email. Click the "Report" button from the home screen, enter your name and select a period for which to generate a report. You can also let the report include weekly dose counts after a certain day. Verify that the generated report contains the correct information and then share it as you like.

Can I import data from another app / a handwritten diary?

Yes, this is possible through the import functionality of the app. Import files need to be in CSV (comma separated value) format (with .csv extension) and should contain the following type of data:

  • Dose import files: dose date (in yyyy-mm-dd format), dose value (decimal), dose confirmation time (hh:mm)
  • INR import files: INR date (in yyyy-mm-dd format), INR value (decimal), INR remark (optional, text)

Please click on the links above to see samples of these files. Please contact us if this doesn't work for you.
