Evaluation of iDECIDE: A Smartphone App for Insulin Dosing Accounting for Alcohol and Exercise

The iDECIDE app will be installed in study participant's smartphone. The app requests from study participants input on food consumed (included food's carbohydrate content), alcohol consumed (included alcohol's carbohydrate content) and exercise plans (including duration and intensity). Based on that input the app suggests insulin bolus dosing.

Study participants will use during the study their own insulin pump and continuous glucose sensor. As inclusion criteria, investigators expect study participants to have been using their insulin pump and continuous glucose sensor for at least one year.
