Brief summary

This study examines the safety of an app-based insulin bolus calculator that utilizes glucose values from a continuous glucose monitor

Detailed description

Individuals with type 1 diabetes and those with type 2 diabetes who are prescribed bolus insulin must decide on an insulin dose for any given meal. This dose is often based on what they are eating and their glucose value. Insulin bolus calculators may be helpful in recommending an insulin dose. This study examines the safety of an app-based insulin calculator manufactured by Welloc (Columbia, MD). This app uses the glucose value and trend arrow, in certain circumstances, to recommend a bolus insulin dose. This study is a single arm trial where continuous glucose monitoring metrics such as time in range will be measured before and after the study participants are given the app.
