What's Happening?
A recent study tracking 865 mental health apps over six years found that more than half (54%) were removed from app stores, with the median app lasting approximately three years. The research, led by Julian Herpertz and John Torous, published in the American
Journal of Psychiatry, highlights that apps designed for serious mental illnesses like schizophrenia and mood disorders had the highest disappearance rates. Surprisingly, features often highlighted in funding pitches, such as in-app chat, video, peer support, gamification, and AI capabilities, did not predict an app's longevity. Instead, simpler functionalities like journaling, goal-setting, data exportability, Spanish language availability, and cross-platform compatibility (iOS and Android) were associated with a 30% to 50% reduced risk of an app vanishing. Being platform-exclusive more than doubled the risk of disappearance. The study also noted that while more apps now have privacy policies, more are also sharing personal health data with third parties.
Why It's Important?
The high attrition rate of mental health apps poses significant challenges for users, particularly those with serious mental illnesses who rely on these tools for continuity of care. The disappearance of a familiar app can disrupt routines and erode trust, making it harder for individuals to manage their conditions. This instability in the digital mental health market means that clinicians and caregivers must exercise greater caution when recommending apps, focusing on a developer's sustainability and data practices rather than just advertised features. The findings suggest a misalignment between what attracts funding (advanced features) and what ensures an app's long-term viability (basic, user-centric functionalities). This impacts the effectiveness of digital mental health interventions and raises questions about the responsibility of developers and investors in providing reliable tools for vulnerable populations.
What's Next?
Clinicians and caregivers are advised to shift their evaluation criteria for mental health apps, prioritizing factors like a company's business model, data ownership policies, and track record of existence over advanced features. Grant programs, health systems, and app-evaluation frameworks may need to incorporate sustainability and data practices more heavily into their assessment processes. This could lead to a greater emphasis on non-commercial developers (academic, government, nonprofit) who were found to be more likely to handle data responsibly and use evidence-based practices. The industry might see a push towards more transparent business models and a focus on core functionalities that ensure long-term user support, especially for underserved populations like those managing psychosis.
Beyond the Headlines
The study uncovers a deeper issue regarding the commercial incentives driving the mental health app market. Venture-backed developers often prioritize features that attract investment rounds, even if these features do not contribute to an app's longevity or user benefit. This creates a market where the most vulnerable populations, such as those with schizophrenia, are functionally unserved by sustainable digital tools. The ethical implications extend to data privacy, as the study found that while privacy policies are more common, data sharing with third parties is also increasing. This highlights a need for stronger regulatory oversight and industry standards that prioritize patient well-being and data security over profit-driven innovation, ensuring that digital mental health tools provide reliable and continuous support.
