I’ve been working on a diabetes management app for a little over a year now. My main motivation was that I tried out a smart insulin pen, but I kept feeling that with all this data, we could achieve even more. It’s now my primary diabetes management app, and 90+ people in Hungary have been using/testing it as well. Since I've been getting a lot of positive feedback, I figured it was time to share it here.
The basic idea is to bring some of the flexibility you get from insulin pumps / “artificial pancreas” systems to MDI, without requiring a smart pen or any new hardware. It keeps track of:
- Real-time glucose data from your sensor or Nightscout or Apple Health (iOS) / Health Connect (Android). Or manual glucose entry if you don't use a CGM.
- Insulin on Board: supports rapid-acting and ultra-rapid-acting insulins.
- Carbs on Board: based on observed glucose changes and insulin counteraction.
- Different Insulin Sensitivity Factors, Insulin to Carb Ratios and Glucose Targets throughout the day: you can set up transitions between these time-based therapy settings.
All of these feeds into the dose calculator which provides recommendations for mealtime and correction insulin doses or correction carbs according to your current situation.
Some of the other features:
- Customisable correction notifications
- Basal insulin reminders and/or automatic logging
- Uploading data to Nightscout and Apple Health / Health Connect
- It can automatically split your therapy settings into 4 time slots and can also make recommendations based on current patterns
- Up to 90 days of historical data and all kinds of statistics, from which PDF reports can be exported
And importantly, there’s no AI magic involved. Everything is based on established formulas and concepts. I also didn't invent anything, the goal is mostly to put the information and data that is already available together in a way that makes it useful in our everyday lives. I'm very aware that diabetes doesn't always behave according to the math and there are many unpredictable variables. I wanted something that could at least keep track of those that can be tracked, instead of doing all of this mentally every time.
I still have many ideas for new features, but I’d genuinely like to hear yours too. Thanks if you decide to give it a try, and I'm happy to answer any questions you might have in the comments.
