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

Inclusion Criteria:

• Be at least 18 years old (at least 19 years old in Alabama and Nebraska, at least 21 years old in Puerto Rico);
• Live in the United States of America;
• Have an iPhone;
• Have installed Apple Research app on your iPhone;
• Be comfortable communicating in written and spoken English;
• Be willing and able to provide informed consent to participate in the Study.

Exclusion Criteria:

• Share your iCloud account, iPhone, or devices that collect health data such as Apple Watch with anyone else, because it could result in sharing another person's health information with the Study, making it challenging for researchers to use your information.

The Study aims to enroll a large and representative group of at least 500,000 participants across the United States of America willing to contribute information about health and wellness over time.
