Mountain View, California–based Twin Health’s approach uses a combination of wearables, AI, and on-demand health coaching to help manage diabetes, prediabetes, and obesity. The company sends users a kit with a continuous glucose monitor, blood pressure cuff, smart scale, and fitness tracker. Together, the devices collect data points on blood sugar, weight, stress, blood pressure, sleep, and activity and feed them into a single app. Using a predictive AI model, the app analyzes all this information to generate a virtual replica of the user’s metabolism—the digital twin.
