Apple Health Study

The Apple Health Study aims to build a diverse and inclusive group of participants to help researchers advance our understanding of how signals and information collected from apps and devices relate to health and may be used to predict, detect, monitor, and manage changes in health.

To enroll, US residents who have an iPhone can download the Apple Research app from the App Store and go through the introduction and informed consent for the Apple Health Study. This study is fully remote, and all are invited to enroll if the eligibility criteria are met.

Participants will be asked to complete tasks and surveys, using their iPhone and Apple Research app which include:

* Selecting the types of data they would like to share with the study such as health and sensor data * Completing tasks and surveys including areas such as personal demographic information, personal medical history, family history, and social determinants of health
