Smartwatch and app study for type 2 diabetes
Part of Hormones & metabolism clinical trials.
This study tests whether combining a smartwatch, a smartphone app, and continuous glucose monitoring can better predict blood sugar levels in people with type 2 diabetes. You would wear a Samsung watch, use a health app, and take photos of your meals.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 75 years old.
- You have type 2 diabetes and are a patient at Johns Hopkins Medicine.
- You use an Android smartphone and a Dexcom G7 or FreeStyle Libre 3 continuous glucose monitor (CGM) with its app.
- You have used your CGM for at least 2 weeks, wearing it at least 50% of the time, and your blood sugar readings are often above target (time in range less than 70%).
- You are willing to wear a Samsung Galaxy Watch at least 12 hours a day and download the Welldoc app, Samsung Health, and Google Health Connect.
- You are willing to take photos of all your meals and use your CGM at least 80% of the time.

This study asks you to wear a glucose monitor and smart ring for several months to help researchers understand how blood sugar changes throughout the day in people with prediabetes or type 2 diabetes. The goal is to learn how lifestyle and medications affect blood sugar control.
This study uses artificial intelligence to better understand how type 2 diabetes progresses in young people. By wearing a continuous glucose monitor, you may help researchers find patterns that could improve future care.
This study tests whether using a smartphone app and a wearable device (like a fitness tracker), along with artificial intelligence (AI), can help people with type 2 diabetes better manage their condition and prevent complications. You would need to provide lifestyle information and use the devices for 3 months.
This 8-week study tests whether using a smartphone app called SnapD along with a continuous glucose monitor (a small sensor that tracks your blood sugar throughout the day) helps people with type 2 diabetes manage their condition better. You'll keep taking your current diabetes medications without changes.
This trial tests using a smartphone to help manage your blood sugar. It's for people with type 2 diabetes who take insulin and whose blood sugar is not well controlled (HbA1c 8% or higher).
This study tests whether a wearable glucose monitor plus a smartphone app can give personalized diet tips. You wear a small sensor for 14 days, log your meals, and take photos of what you eat.
