How does the app calculate my Diabetes Management Indicator (DMI)?
First, the app checks if you logged 21 blood sugar values in the last 7 days (including the current day). If that’s fulfilled, it checks if you logged those values on at least 4 out of the 7 days. That’s important because otherwise one could log 21 values in just 1 day and get an estimate that’s most likely far away from the average blood sugar level.
If the two criteria above are fulfilled, the app takes the average of your blood sugar values, puts it into a formula and calculates your Diabetes Management Indicator (DMI). You don’t need to crunch any numbers, the app does it all for you!
Which data is taken into account?
The Diabetes Management Indicator (DMI) is calculated using your logged blood sugar values (not CGM or sensor data). If you have 21 blood sugar values logged on at least 4 of the past 7 days (including the current day), then the app can also take into account the past 90 days of data. The app looks back at your past data until it detects a “gap” in it. A gap in your data means that there were more than 2 days in a row where you didn’t log any blood sugar values. If a gap is detected, then no further values are taken into account.
Why is my Diabetes Management Indicator (DMI) not displayed?
Without enough data, Diabetes Management Indicator (DMI) can’t be calculated and displayed. That’s when “-” is displayed. If you tap on the Diabetes Management Indicator (DMI) field on the home screen you’ll see a detailed explanation with information on how much progress you’ve already made. Keep feeding blood sugar values into your logbook and you’ll have your Diabetes Management Indicator (DMI) in no time.
It could happen that from one day to another your DMI disappears. That’s because the app always looks back at the last 7 days, including the current day, and checks if you have 21 blood sugar values logged on at least 4 out of those 7 days. It can happen that yesterday those criteria were fulfilled but today they are not. Just keep on logging and it will come back :)
Why is my DMI not changing?
The value doesn’t change with every new blood sugar value you enter in the app. It might be that your values are so stable, that a new value simply doesn’t impact your estimate.
What does the color coding of the icon mean?
The Diabetes Management Indicator (DMI) has three different ranges. A DMI of 6.5% or below is considered very good, and the icon on the DMI widget will appear green. A medium DMI, which falls between 6.5% and 7.5%, will be indicated by an orange icon. If the DMI is above 7.5%, suggesting that diabetes management might need attention, the icon will be red.
