Health Apps Under Scrutiny: Experts Warn of Risks Without Proper Guidance

BERLIN — From step counters to patient portals, health apps have become ubiquitous tools for managing wellness, chronic conditions, and even mental health. But as their popularity surges, medical experts are sounding alarms about potential risks—including misinformation, data privacy breaches, and unintended harm—when users navigate these digital tools without professional oversight.

Dr. Helena Fischer, Editor of Health at World Today Journal and a physician with over a decade of experience in internal medicine, explains that while health apps offer unprecedented convenience, their rapid proliferation has outpaced safeguards. “The promise of empowerment is real, but so are the pitfalls,” she notes. “Without proper guidance, users may misinterpret data, delay necessary care, or expose sensitive health information to third parties.”

A recent warning from the European Medicines Agency (EMA) underscores these concerns, highlighting cases where users of unregulated apps received inaccurate medical advice or misdiagnosed conditions based on flawed algorithms. In the Netherlands, where health app adoption is among the highest in Europe, regulators have begun auditing popular platforms for compliance with GDPR and medical device standards.

The Double-Edged Sword of Digital Health

Health apps span a broad spectrum, from fitness trackers like Fitbit to comprehensive patient portals such as the Dutch MijnZorgNet, which allows users to access medical records, schedule appointments, and communicate with providers. While these tools can improve adherence to treatment plans and reduce administrative burdens, experts caution that their benefits are not universal.

“The assumption that all users have the health literacy to interpret app data correctly is flawed,” says Dr. Anouk van Leeuwen, a public health researcher at the Dutch National Institute for Public Health and the Environment (RIVM). In a 2025 study published in The Lancet Digital Health, van Leeuwen and her team found that nearly 30% of users misinterpreted app-generated health recommendations, leading to unnecessary anxiety or complacency. For example, step counters that reward users for hitting daily targets may inadvertently encourage overexertion in individuals with heart conditions.

Mental health apps, in particular, have come under fire. A 2024 report by the American Psychological Association (APA) found that while apps like Headspace and Woebot can provide short-term relief for mild anxiety, they are not substitutes for professional therapy. The report warned that users with severe depression or suicidal ideation might delay seeking aid if they rely solely on automated interventions.

Data Privacy: A Growing Concern

The collection and storage of sensitive health data by apps have raised red flags among regulators. In 2023, the Dutch Data Protection Authority (AP) fined a popular Dutch health app €450,000 for failing to secure user data, which was exposed in a breach affecting over 100,000 individuals. The incident highlighted vulnerabilities in apps that lack robust encryption or share data with third-party advertisers.

“Patients often assume their data is protected under medical confidentiality laws, but many health apps operate outside these regulations,” explains Dr. Marjolein Boumans, a legal scholar specializing in digital health at Tilburg University. “If an app isn’t classified as a medical device, it may not be subject to the same privacy standards as hospitals or clinics.”

The European Union’s European Health Data Space (EHDS), set to fully launch in 2027, aims to address these gaps by creating a unified framework for data sharing and privacy. Until then, experts urge users to scrutinize app permissions and opt for platforms certified by organizations like Health On the Net (HON).

Who Is Most at Risk?

While health apps can benefit nearly anyone, certain groups are more vulnerable to their risks:

• Chronically ill patients: Those managing conditions like diabetes or hypertension may misinterpret app data, leading to incorrect medication adjustments. A 2025 study in JAMA Internal Medicine found that 15% of diabetes patients using glucose-tracking apps miscalculated insulin doses based on app recommendations.
• Older adults: Seniors may struggle with app interfaces or overlook disclaimers, increasing the likelihood of misuse. The World Health Organization (WHO) recommends that older users receive in-person training before adopting health apps.
• Individuals with mental health conditions: Apps offering cognitive behavioral therapy (CBT) or mood tracking may provide false reassurance, delaying professional intervention. The APA advises users to consult a therapist before relying on such tools.
• Low-income populations: Users without access to regular healthcare may turn to apps as a substitute, risking missed diagnoses or untreated conditions. A 2024 Commonwealth Fund report found that 22% of low-income app users in Europe delayed seeing a doctor due to overreliance on digital tools.

Regulation and the Path Forward

Governments and health organizations are beginning to respond to these challenges. In the Netherlands, the Health and Youth Care Inspectorate (IGJ) now requires apps that diagnose or treat medical conditions to undergo rigorous testing before entering the market. Similar measures are being adopted across the EU, with the EMA developing a certification program for health apps.

“The goal isn’t to stifle innovation but to ensure that apps meet basic safety and efficacy standards,” says Dr. Van Leeuwen. “Users should look for apps that are transparent about their limitations and provide clear guidance on when to seek professional help.”

For now, experts recommend the following precautions:

• Verify the app’s credentials: Look for certifications from reputable organizations like HON or the NHS Digital Health Apps Library.
• Read the fine print: Understand how your data will be used and shared. Opt out of third-party data sharing when possible.
• Consult a professional: Discuss app use with your doctor or therapist, especially if you have a chronic condition or mental health concerns.
• Use apps as supplements, not substitutes: Treat health apps as tools to complement—not replace—professional care.

Key Takeaways

• Health apps can improve health outcomes but carry risks, including misinformation, data breaches, and delayed care.
• Vulnerable groups—such as chronically ill patients, older adults, and those with mental health conditions—are most at risk of harm.
• Regulators are tightening oversight, but users must remain vigilant about data privacy and app credibility.
• Experts emphasize the need for professional guidance to maximize benefits and minimize risks.

What’s Next?

The European Commission is expected to release updated guidelines for health app regulation in Q3 2026, with a focus on data security and user education. In the meantime, users are encouraged to report problematic apps to their national health authorities. For official updates, visit the European Commission’s Health Portal.
