Summary

This study tests a new way for people to share their health data from wearables like smartwatches to help improve heart disease prevention. Researchers want to see if this approach can include groups often left out of research, such as women and people with lower incomes. About 450 adults will join this pilot phase, donating data for up to 5 years while keeping full control over what they share.
