Apple is rolling out 3 new health studies, and anyone with an iPhone can participate - here's how to sign up

To download the app, go to the app store on an iOS device and search for Apple Research.

Once you open the app, you'll be greeted with an explainer laying out how Apple intends to use your health data as a study participant.

Apple is quick to reassure would-be participants that the studies keep their information confidential, along with other privacy disclaimers.

There are three studies currently open: women's health, heart and movement, and hearing. For this walkthrough, I started the process of enrolling in the hearing study.

The app lays out the expectations for participating in the study. For the hearing study, most of the data is collected passively, along with periodic surveys and hearing tests.

Before enrolling, Apple collects users' signatures consenting to the study, as well as demographic information.

Here are all the data points that the hearing study would collect from a user's phone day to day.

After enrolling, users are presented with a dashboard that assigns them tasks and tracks their progress in the study.
