Note: This app is only for use by participants in the WCWH Cohort Study.

The Whole Communities–Whole Health app, called Hornsense, is the primary portal for cohort participants to engage with the study. Through the app, participants can track study materials they receive including sample collection kits, in-home sensing devices, and wearable devices. Participants also complete periodic surveys about their health, well-being, and environment, all delivered through the app. A built-in dashboard allows participants to view the data they have contributed, from data sensed on their smartphones to survey responses and sample results, and compare it to aggregated, anonymized data from their broader community.
