UCLA launched a new study on Tuesday, sponsored by and in collaboration with Apple, designed to help revolutionize detection and treatment of depression.

It’ll follow the daily routines of Apple Watch and iPhone users, and examine the relationship between this data and symptoms of depression and anxiety.

Scientists want to know if the health data an Apple Watch collects can be used to diagnose COVID-19. There are multiple research studies currently open to those with Apple’s wearable.

Participants contribute to the goal of detecting the illness before the wearer knows they’re sick.
