Summary

This pilot study tests whether personalized coaching messages written by an AI can encourage people to be more active. Fifty adults with an iPhone and Apple Watch will receive daily texts for two weeks—some personalized, some generic. The goal is to see if the AI-generated prompts lead to more physical activity, which could later be used in the My Heart Counts app.
