What this study is about
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.
View original scientific description
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.
Primary outcome measures
Health Status
Time frame: Baseline and every 6 months until study end (up to 5 years)
Assessed by participant self-report as well as clinical health records and claims data. The initial count and change over time in the number and type of health conditions such as cardiovascular, circulatory, cognition, hearing, mental health, metabolic, mobility, neurologic, respiratory, sex and gender, reproduction, hormones, sleep, and health events such as hospitalizations, procedures or falls.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
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;

- 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.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
