SAN FRANCISCO (AP) — Jody Kearns doesn’t like to spend time obsessing about her Parkinson’s disease. The 56-year-old dietitian from Syracuse, New York, had to give up bicycling because the disorder affected her balance. But she still works, drives and tries to live a normal life.

Yet since she enrolled in a clinical study that uses her iPhone to gather information about her condition, Kearns has been diligently taking a series of tests three times a day. She taps the phone’s screen in a certain pattern, records a spoken phrase and walks a short distance while the phone’s motion sensors measure her gait.

“The thing with Parkinson’s disease is there’s not much you can do about it,” she said of the nervous-system disorder, which can be managed but has no cure. “So when I heard about this, I thought, ‘I can do this.'”

Smartphone apps are the latest tools to emerge from the intersection of health care and Silicon Valley, where tech companies are also working on new ways of bringing patients and doctors together online, applying massive computing power to analyze DNA and even developing ingestible “smart” pills for detecting cancer.

More than 75,000 people have enrolled in health studies that use specialized iPhone apps, built with software Apple Inc. developed to help turn the popular smartphone into a research tool. Once enrolled, iPhone owners use the apps to submit data on a daily basis, by answering a few survey questions or using the iPhone’s built-in sensors to measure their symptoms.

Scientists overseeing the studies say the apps could transform medical research by helping them collect information more frequently and from more people, across larger and more diverse regions, than they’re able to reach with traditional health studies.

A smartphone “is a great platform for research,” said Dr. Michael McConnell, a Stanford University cardiologist, who’s using an app to study heart disease. “It’s one thing that people have with them every day.”

While the studies are in early stages, researchers also say a smartphone’s microphone, motion sensors and touchscreen can take precise readings that, in some cases, may be more reliable than a doctor’s observations. These can be correlated with other health or fitness data and even environmental conditions, such as smog levels, based on the phone’s GPS locater.

Others have had similar ideas. Google Inc. says it’s developing a health-tracking wristband specifically designed for medical studies. Researchers also have tried limited studies that gather data from apps on Android phones.

But if smartphones hold great promise for medical research, experts say there are issues to consider when turning vast numbers of people into walking test subjects.

The most important is safeguarding privacy and the data that’s collected, according to ethics experts. In addition, researchers say apps must be designed to ask questions that produce useful information, without overloading participants or making them lose interest after a few weeks. Study organizers also acknowledge that iPhone owners tend to be more affluent and not necessarily an accurate mirror of the world’s population.

Apple had previously created software called HealthKit for apps that track iPhone owners’ health statistics and exercise habits. Senior Vice President Jeff Williams said the company wants to help scientists by creating additional software for more specialized apps, using the iPhone’s capabilities and vast user base — estimated at 70 million or more in North America alone.

“This is advancing research and helping to democratize medicine,” Williams said in an interview.

Apple launched its ResearchKit program in March with five apps to investigate Parkinson’s, asthma, heart disease, diabetes and breast cancer. A sixth app was released last month to collect information for a long-term health study of gays and lesbians by the University of California, San Francisco. Williams said more are being developed.

For scientists, a smartphone app is a relatively inexpensive way to reach thousands of people living in different settings and geographic areas. Traditional studies may only draw a few hundred participants, said Dr. Ray Dorsey, a University of Rochester neurologist who’s leading the Parkinson’s app study called mPower.

“Participating in clinical studies is often a burden,” he explained. “You have to live near where the study’s being conducted. You have to be able to take time off work and go in for frequent assessments.”

Smartphones also offer the ability to collect precise readings, Dorsey added. One test in the Parkinson’s study measures the speed at which participants tap their fingers in a particular sequence on the iPhone’s touchscreen. Dorsey said that’s more objective than a process still used in clinics, where doctors watch patients tap their fingers and assign them a numerical score.

Some apps rely on participants to provide data. Elizabeth Ortiz, a 48-year-old New York nurse with asthma, measures her lung power each day by breathing into an inexpensive plastic device. She types the results into the Asthma Health app, which also asks if she’s had difficulty breathing or sleeping, or taken medication that day.

“I’m a Latina woman and there’s a high rate of asthma in my community,” said Ortiz, who said she already used her iPhone “constantly” for things like banking and email. “I figured that participating would help my family and friends, and anyone else who suffers from asthma.”

None of the apps test experimental drugs or surgeries. Instead, they’re designed to explore such questions as how diseases develop or how sufferers respond to stress, exercise or standard treatment regimens. Stanford’s McConnell said he also wants to study the effect of giving participants feedback on their progress, or reminders about exercise and medication.

In the future, researchers might be able to incorporate data from participants’ hospital records, said McConnell. But first, he added, they must build a track record of safeguarding data they collect. “We need to get to the stage where we’ve passed the privacy test and made sure that people feel comfortable with this.”

Toward that end, the enrollment process for each app requires participants to read an explanation of how their information will be used, before giving formal consent. The studies all promise to meet federal health confidentiality rules and remove identifying information from other data that’s collected. Apple says it won’t have access to any data or use it for commercial purposes.

Some studies will always require in-person interaction or supervision by a doctor, experts say. But by reaching more people and gathering more data, advocates say smartphone apps can help doctors answer more subtle questions about a disease.

“Diseases like asthma are very complicated. They’re not caused by a single gene or environmental influence,” said Eric Schadt, a genomics professor who’s using an iPhone app to study asthma at New York’s Icahn School of Medicine at Mount Sinai. “The only hope you have of really going further in resolving this disease is for researchers to get to more people.”

COMMENTARY: The Biases We Don’t See — Preventing AI-Driven Inequality in Health Care

For decades, medicine promoted false assumptions about Black bodies. Black patients were told they had lower lung capacity, and medical devices adjusted their results accordingly. That practice was not broadly reversed until 2021. Up until 2022, a common medical formula used to measure how well a person’s kidneys were working automatically gave Black patients a higher score simply because they were Black. On paper, this made their kidneys appear healthier than they truly were. As a result, kidney disease was sometimes detected later in Black patients, delaying critical treatment and referrals.

Technology is sold to us as neutral, objective, and free of human flaws. We are told that computers remove emotion, bias, and error from decision-making. But for many Black families, lived experience tells a different story. When technology is trained on biased systems, it reflects those same biases and silently carries them forward.

We have seen this happen across multiple industries. Facial recognition software has misidentified Black faces at far higher rates than White faces, leading to wrongful police encounters and arrests. Automated hiring systems have filtered out applicants with traditionally Black names because past hiring data reflected discriminatory patterns. Financial algorithms have denied loans or offered worse terms to Black borrowers based on zip codes and historical inequities, rather than individual creditworthiness. These systems did not become biased on their own. They were trained on biased data.

Healthcare is not immune.

These biases were not limited to software or medical devices. Dangerous myths persisted that Black people feel less pain, contributing to undertreatment and delayed care. These beliefs were embedded in modern training and practice, not distant history. Those assumptions shaped the data that now feeds medical technology. When biased clinical practices form the basis of algorithms, the risk is not hypothetical. The bias can be learned, automated, and scaled.

For us in the Black community, this creates understandable fear and mistrust. Many families already carry generational memories of medical discrimination, from higher maternal mortality to lower life expectancy to being dismissed or unheard in clinical settings. Adding AI biases could make our community even more apprehensive about the healthcare system.

As a physician, I know how much trust patients place in the healthcare system during their most vulnerable moments. As a Black woman, I understand how bias can shape experiences in ways that are often invisible to those who do not live them. As a mother of two Black children, I think constantly about the systems that will shape their health and well-being. As a legislator, I believe it is our responsibility to confront emerging risks before they become widespread harm.

That is why I am the author of Senate Bill (SB) 503. This bill aims to regulate the use of artificial intelligence in healthcare by requiring developers and users of AI systems to identify, mitigate, and monitor biased impacts in their outputs to reduce racial and other disparities in clinical decision-making and patient care.

Currently under consideration in the State Assembly, SB 503 was not written to slow innovation. In fact, I encourage it. But it is our duty must ensure that every tool we in the healthcare field helps patients rather than harms them.

The health of our families depends on it.

On Jan. 27, California released its Fifth Master Plan for Aging Annual Report,titled “Focusing on What Matters Most,” outlining the state’s progress and priorities as its population rapidly grows older.

The report, issued by the California Health and Human Services Agency (CalHHS), provides updates on the Master Plan for Aging’s “Five Bold Goals”: housing, health, inclusion and equity, caregiving, and affordability.

The report comes as Californians aged 60 and older now outnumber those under 18 for the first time, a demographic shift expected to accelerate over the next decade.

Launched in 2021, the Master Plan for Aging takes a “whole-of- government” and “whole-of-society” approach, coordinating state agencies, local governments, community organizations, and private partners. The annual report highlights significant milestones, including more than 100 California communities joining AARP’s Age-Friendly Network and $4 million in state funding awarded to local organizations to develop aging and disability action plans in 30 communities statewide.

The report also underscores California’s leadership at the national level, noting that dozens of states have followed its example and that federal legislation inspired by the plan was reintroduced in the U.S. Senate in December 2025.

CalHHS Secretary Kim Johnson emphasized the plan’s focus on equity and resilience amid ongoing challenges.

“The Master Plan for Aging continues to provide a vision, a focus, and a platform for collaboration,” Johnson said. “Equity is at the center of all that we do.”

Looking ahead, the report notes that by 2030, one in four Californians will be age 60 or older, positioning the Master Plan for Aging as a central framework for meeting the state’s long-term social, economic, and health needs.

On Tuesday, Feb. 3, seven candidates took the stage at the historic Ruth Williams–Bayview Opera House in San Francisco for the gubernatorial debate, hosted by the Black Action Alliance (BAA) in partnership with KTVU and sister station KTTV Fox 11 in Los Angeles.

For many voters, it marked a first opportunity to hear directly from several candidates seeking to lead the nation’s most populous state.

Crucial topics and issues addressed throughout the debate included housing, crime, immigration, climate change, health care and homelessness.

The debate was moderated by KTVU political reporter Greg Lee alongside KTVU’s Andre Senior and KTTV Fox 11’s Marla Tellez.

Candidates also addressed inflation and the rising costs across the state, impacting everything from groceries to childcare and health care.

Thurmond vowed to generate 2.3 million units of housing by placing 12 units on each parcel of available land in the 58 counties of California. Steyer agreed that billionaires should pay their fair share of taxes.

Hilton wanted to cut taxes, help working-class families, and end the Democrats “climate crusade and insane regulations.”

Yee offered a more transparent governmental approach with accountability, given the state’s debt.

Gonzalez said, “This debate was a great way to see who has great ideas and who has substance.”

“It’s important to have the debate within a community that requires the most,” said business leader Linda Fadekye.

Attendees included State Controller Malia Cohen, representatives of the National Coalition of 100 Black Women, the National Coalition of 100 Black Men, the San Francisco African American Chamber of Commerce, and Black Women Organized for Political Action, among others.

Event host, the Black Action Alliance (BAA) was established to amplify the voices of the Bay Area’s Black community, whose perspectives have too often been overlooked in politics and public policy.

Loren Taylor, CEO of BAA, said it was important to bring the event to the Bayview in San Francisco and shared his organization’s mission.

“The Black Action Alliance (BAA) stands for practical, community-driven solutions that strengthen public safety, address homelessness, support small businesses, expand affordable housing, and ensure access to quality education—issues at the heart of the Black experience in the Bay Area,” said Taylor.

California’s primary election will take place on June 2 and the general election will take place on Nov. 3.
