Health apps—from step counters to patient portals—have become a staple in modern wellness routines, but experts warn they may not be as safe or effective as users assume. Without proper guidance, these digital tools could pose unexpected risks to personal health, according to a leading researcher.
Dr. Anja de Kruif, a health scientist at Amsterdam UMC, emphasized the need for professional oversight when using health-related apps. “Many people rely on these tools daily, but without the right support, they might misinterpret data or overlook critical health signals,” she said. Her concerns highlight a growing gap between the convenience of digital health solutions and their real-world impact on users.
Apps Can Mislead Users, Study Finds
De Kruif’s research, published in the journal Digital Health, analyzed user interactions with popular health apps. The findings suggest that without expert interpretation, users may draw incorrect conclusions about their health. For example, step counters might encourage excessive activity in individuals with certain conditions, while symptom-tracking apps could lead to unnecessary anxiety or delayed medical care.
“These tools are designed to empower users, but they can likewise create confusion,” de Kruif noted. “A person might see a spike in their heart rate on an app and assume it’s harmless, when in reality, it could signal an underlying issue that requires medical attention.”

Who’s Most at Risk?
The study identified several groups particularly vulnerable to the pitfalls of unguided app use:
- Older adults, who may struggle to navigate app interfaces or interpret data accurately.
- Individuals with chronic conditions, such as diabetes or heart disease, who rely on apps for daily management.
- People with mental health concerns, who might use apps to track mood or symptoms but lack professional context.
De Kruif stressed that these risks don’t mean health apps should be avoided altogether. Instead, she advocates for better integration with healthcare providers. “Apps can be incredibly useful, but they should complement—not replace—professional medical advice,” she said.
What Users Can Do
For those who use health apps regularly, experts recommend a few key steps to minimize risks:
- Consult a healthcare provider: Before relying on an app for medical decisions, discuss its use with a doctor or nurse.
- Verify the source: Choose apps developed or endorsed by reputable health organizations, such as hospitals or government agencies.
- Use apps as a tool, not a diagnosis: Treat app data as supplementary information, not a substitute for professional evaluation.
- Monitor for red flags: If an app’s recommendations seem extreme or contradictory to medical advice, seek clarification from a provider.
Public health advocates say the findings underscore the need for clearer guidelines around digital health tools. “As these apps become more advanced, so should our approach to using them safely,” said a spokesperson for the Dutch National Institute for Public Health and the Environment (RIVM). The agency is currently reviewing recommendations for app developers and healthcare providers to improve user safety.
For now, de Kruif’s message is clear: “Health apps can be a valuable part of wellness routines, but they’re not foolproof. Users should approach them with the same caution they would any other health resource.”
The rise of health apps reflects a broader shift toward digital wellness, but experts caution that convenience shouldn’t come at the expense of accuracy. As more people turn to these tools for guidance, the call for better oversight and education grows louder. Until then, users are urged to stay informed and seek professional input when in doubt.
