ClinConnect Summary

This clinical trial is exploring a new mobile app designed to help adults with type 1 diabetes, as well as other forms of diabetes that involve insulin deficiency, exercise more regularly and confidently. The app will provide personalized support, using information from continuous blood sugar monitoring, exercise habits, mood, and sleep patterns to encourage healthier behaviors. The goal is to make it easier for people with diabetes to stay active, which can be challenging due to their condition.

To be eligible for this study, participants must be between 30 and 65 years old and diagnosed with type 1 diabetes or another form of insulin deficiency. They should also currently exercise less than once a week and own a smartphone with internet access. Participants will need to provide recent data from a continuous glucose monitor and an insulin delivery method, like a pump or pen. Throughout the study, participants can expect to use the app over a certain period, receiving ongoing support and insights tailored to their individual health needs. This trial is not yet recruiting, but it aims to improve the lives of those managing diabetes by making exercise more accessible.
