NCT ID NCT06098729
First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study tested a mobile app that gives personalized encouragement and health insights based on blood sugar, exercise, mood, and sleep patterns. The goal was to help 24 middle-aged adults with type 1 diabetes or similar conditions exercise more often and confidently. The app aims to make it easier to stay active despite the challenges of managing diabetes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- mobile application delivering personalized encouragement and data-driven health insights
- What this could lead to
- If it works, this could help people with type 1 diabetes exercise more often and with greater confidence, improving their overall health.
- What could go wrong
- This is a small feasibility study with only 24 participants, so results may not apply to everyone. The app's accuracy in predicting exercise lapses is still modest (target 80%).
