Study Details

Study Description

Brief Summary

The main purpose of this study is to determine whether combining meal, glucose, and insulin data in a web-based system will improve management of type 1 diabetes (T1D). No study drug will be given. The study will last about 18 weeks.

Arms and Interventions

Arm Intervention/Treatment
Combined Diabetes Management Data

Participants with type 1 diabetes will use a meal tagging application (app) and fitness tracker. They will upload these data to a web portal where they will be matched with data from their continuous glucose monitor and insulin pump. Combined data will be used for diabetes management.

Other: Meal-Tagging App
Meal tagging app to capture frequently eaten meals and test meals for 16 weeks.

Device: Fitness Tracker
Fitness tracker will be worn around the clock for 16 weeks.
