Mobile health apps have become one of the most visible and fast-growing parts of digital health. The World Health Organization describes digital health as a way to support equitable access to quality health services and make health systems more efficient and sustainable. Within that wider digital health landscape, mobile health has grown rapidly as more people use phones to access health information, track symptoms, support self-care, and stay connected with healthcare services. IQVIA reported in its 2024 digital health trends review that the number of digital health apps stands at 337,000, showing how large and mature this app ecosystem has become
What are mobile health apps?
Mobile health, often called mHealth, refers to the use of mobile technology for health purposes. WHO explains that mHealth includes the use of mobile phones to prevent, manage, and treat disease and risk factors by supporting both patients and healthcare providers, including through text messaging and mobile phone applications. The FDA similarly notes that mobile apps can help people manage their health and wellness, promote healthy living, and access useful information when and where they need it.
In practice, mobile health apps now cover a broad range of functions. A recent health technology overview from the National Center for Biotechnology Information notes that health apps are used across disease areas such as chronic disease, mental health, medication adherence, sleep, fitness, and vital sign measurement. The same review groups them broadly into informational apps, diagnostic apps, disease-management apps, and fitness-tracking apps. This variety is one of the main reasons mobile apps have become so influential in healthcare.
Why mobile health apps are rising so quickly
One of the main reasons for this rise is that mobile phones are already part of daily life. WHO has noted that an increasing proportion of the population is accessing health information and services through mobile phones, and that solutions ranging from SMS to complex smartphone apps have been developed to improve health access, knowledge, and behaviors. Because mobile phones are widespread and can reach even remote settings, they offer a practical platform for delivering healthcare support at scale.
The growth of mobile health apps was also accelerated by broader changes in healthcare delivery. AHRQ PSNet reported that demand for digital healthcare, including telemedicine and healthcare-related apps, accelerated sharply during the COVID-19 pandemic. AHRQ also notes that digital tools and smartphone-based apps are becoming increasingly important in behavioral healthcare, where workforce shortages and access gaps have pushed the system toward technology-supported models of care.
Another reason for growth is that mobile apps fit the shift from episodic care to continuous care. Unlike traditional care models that depend mainly on appointments, mobile apps can support health tracking, reminders, symptom logging, education, and communication between visits. That makes them valuable in modern healthcare, where prevention, self-management, and ongoing monitoring are becoming more important.
1. Supporting self-management and chronic disease care
A major role of mobile health apps is helping people manage their own health more actively. WHO states that mHealth helps prevent, manage, and treat noncommunicable diseases and their risk factors. WHO’s broader mHealth report also notes that digital health, and specifically mHealth, has been shown to improve quality and coverage of care, increase access to health information and services, and promote positive health behavior change related to acute and chronic disease prevention.
This is especially important for chronic disease management. The NCBI overview highlights that many health apps are built for condition-specific needs such as diabetes, cardiovascular disease, chronic obstructive pulmonary disease, medication adherence, and symptom tracking. In these cases, a mobile app can become a practical day-to-day support tool rather than just an information source.
2. Expanding prevention, wellness, and healthy behavior change
Not all mobile health apps are designed for diagnosed illness. Many are built for general wellbeing, healthy living, and risk reduction. FDA notes that mobile apps can promote healthy living, while IQVIA’s 2024 review describes large segments of patient-facing digital health apps as health and wellness apps, self-care support apps, and medication management apps. WHO’s Be He@lthy, Be Mobile initiative also shows how app-based and mobile-supported programs can be applied to areas such as physical activity, hearing health, oral health, hypertension, stress, and dementia support.
This preventive role matters because healthcare is no longer focused only on treatment after illness becomes severe. Mobile apps help move care closer to everyday life, where behavior, adherence, and self-awareness strongly influence long-term outcomes. That is one reason they have become so central to modern healthcare transformation.
3. Strengthening behavioral health access and support
Behavioral health is one of the areas where healthcare apps have grown especially quickly. AHRQ notes that the role of apps in behavioral healthcare is growing, partly because of workforce shortages and unmet need, and that these technologies can help connect people and information across time and location. This makes them potentially valuable for integrating behavioral health with primary care and supporting treatment and recovery.
That does not mean every mental-health app is equally effective, but it does explain why this category has expanded so rapidly. Where care access is limited, smartphone-based support can offer education, symptom tracking, guided exercises, monitoring, and connection points that are easier to reach than traditional services alone.
4. Enabling remote monitoring and patient-generated health data
Another major reason mobile health apps are rising is their ability to collect and share patient-generated data. The NCBI overview notes that smartphones and connected wearables can capture health-related data such as steps, weight, breathing, heart rate, sleep, and other metrics, while some apps also rely on manual symptom entry. This makes the smartphone a convenient platform for ongoing observation outside the clinic.
This data can become clinically useful when it is connected to healthcare teams. A case report in npj Digital Medicine showed that patient-generated data from a smartphone asthma app could be shared into an Epic electronic health record, allowing a pulmonologist to review inhaler use and peak flow data and respond when needed. The article describes this type of data sharing as an opportunity for remote patient monitoring and timely intervention to prevent worsening chronic illness.
5. Improving patient engagement and convenience
One of the biggest advantages of mobile health apps is that they meet people where they already are: on their phones. FDA notes that these tools help users access health information when and where they need it. WHO also emphasizes that mHealth can improve access to health information, services, and skills. Together, these qualities make mobile apps well suited for reminders, education, self-tracking, and more continuous patient engagement.
For healthcare systems, this can translate into a more connected model of care. Instead of relying only on occasional appointments, care can be supported between visits through notifications, progress tracking, symptom reporting, and digital communication. That is a major reason mobile apps are increasingly viewed as part of the healthcare delivery model rather than just optional consumer tools.
6. Why regulation and quality matter
The rapid rise of mobile health apps has also created a quality challenge. FDA makes clear that some mobile apps qualify as mobile medical apps or device software functions and therefore fall under regulatory oversight, especially when they pose greater risk if they do not work as intended. At the same time, many health-related apps are general wellness or information tools rather than regulated medical devices. This means the marketplace includes products with very different levels of clinical risk, evidence, and oversight.
The NCBI overview also warns that evidence quality is uneven. It notes that in one systematic review only 1 in 15 applications scored above “very poor” on an evidence-based rating checklist, and it highlights the need for stronger guidance, better evidence, and more informed app selection by clinicians and the public. This is a critical point: growth alone does not guarantee safety, accuracy, or clinical usefulness.
7. Privacy, security, and trust challenges
As mobile health apps become more embedded in healthcare, privacy and security become more important. HHS states that building privacy and security protections into mobile health technologies enhances their value and may be required under laws such as the HIPAA Privacy, Security, and Breach Notification Rules in certain contexts. HHS also points developers to a federal interactive tool to help determine which legal and regulatory requirements may apply to a health-related app.
Trust is therefore a core issue in the rise of health apps. Users may be willing to track symptoms, behavior, or sensitive health data on a phone, but adoption will be weaker if they do not trust how that data is stored, shared, or used. For healthcare providers and organizations, privacy and security are not optional add-ons; they are central to whether a mobile health solution is acceptable in real care settings.
8. Integration with health systems is the next big step
WHO has pointed out that governments often struggle to assess, scale, and integrate mobile health solutions, citing issues such as disconnected pilot projects, lack of interoperability with existing health architectures, and limited standards for comparing fast-evolving digital solutions. This means the future success of mobile health apps depends not just on app downloads, but on whether they can be integrated into real health systems and care pathways.
That is why initiatives such as WHO’s Be He@lthy, Be Mobile are important. The program helps countries build mHealth infrastructure, provides implementation handbooks, and offers evidence-based content libraries that can be adapted across multiple health topics. The rise of mobile health apps is therefore moving from isolated consumer tools toward more structured, scalable, and health-system-oriented models.
Conclusion
The rise of mobile health apps in healthcare is not just a technology trend. It reflects a deeper shift in how healthcare is delivered, experienced, and supported. Mobile apps have grown because they fit the realities of modern care: people want easier access, more continuous support, more self-management tools, and better communication between visits. They now play important roles in chronic disease care, wellness and prevention, behavioral health, remote monitoring, and patient engagement. At the same time, their long-term value depends on evidence quality, privacy, regulation, interoperability, and thoughtful integration into healthcare systems.
