As the market for smart speakers like Amazon’s Alexa continues to expand, there is a potential for these devices to help enhance the health of users. But, while the app stores of these devices are full of apps in the health and fitness categories, a review led by UNC School of Medicine researchers found that many of the apps currently available don’t have much at all to do with health.
Researchers found that many apps do not provide a clear health focus despite being labeled as such. Most are focused on health education or fitness. And very few target patients, caregivers, older adults, or those with disabilities — populations that may benefit most from this technology.
Additionally, apps for monitoring health and wellness are rare.
In the study, published in the JMIR mHealth and uHealth, a medical informatics journal, researchers examined apps released in the health and fitness categories of the app stores for hands-free, voice-activated assistants, including the Amazon Alexa and Google Assistant. Study authors examined information provided by vendors and reviewer ratings, while also analyzing app features, target audiences, age groups, and content categories such as nutrition, health monitoring and education.
As the U.S. smart speaker market for voice assistants like Amazon Alexa expands and adoption rises, these devices can be a medium through which educational and interventional information is delivered with just a simple voice command. According to the study says, this could improve access to information for people with limited vision, physical limitations, and individuals with low literacy. However, these apps and devices are not without security and privacy concerns.
“The lack of HIPAA [Health Insurance Portability and Accountability Act] compliant platforms and restrictions from Amazon and Google for publishing apps that focus on health monitoring and delivery of care are barriers to the release of potentially impactful voice-assistant apps that could help to improve health outcomes,” says senior author Arlene Chung, MD, MHA, associate director of Program on Health and Clinical Informatics at the UNC School of Medicine.
The voice-assistant app market has not yet evolved like the current mobile phone health app market, which focuses on chronic diseases, health monitoring, and self-management. But there has been a sharp uptick in these mobile apps released and this trend is expected to continue for voice-assistant apps. Chung said, while there is much potential for these apps to enhance health, the current market does not offer many apps to meet the needs of patients.
