What this trial studies

The Apple Health Study aims to gather a diverse group of participants to enhance understanding of how data collected from apps and devices can relate to various health aspects, including mental health, sleep, exercise, hormones, and metabolic health. Participants will use their iPhones and the Apple Research app to share health and sensor data, complete surveys, and provide personal and medical history. This observational study focuses on building a comprehensive dataset that can help predict, detect, monitor, and manage health changes over time.
