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.
