Limitations of the New ISO Standard for Health and Wellness Apps.

Software apps for health and wellness are proliferating rapidly.1 Policy makers, health-care providers, and consumers can benefit from assessment and standardisation of these apps, to support decision making in a rapidly developing field. Recognising this unmet need, the International Organization for Standardization (ISO) published a standard in July, 2021, with the purpose of defining a framework for quality assessment and labelling of health apps.2 The framework defined by the standard comprises four subscales: healthy and safe, easy to use, secure data, and robust build, with corresponding questions and proposed evidence standards for those seeking to evaluate the apps in question.
