Are you longing for a better and happier self? There is a plethora of smartphone applications available in app stores that promise to help you reach that goal. Many, if not most, of these apps would not intuitively be considered as health apps or even medical apps. Accordingly, they often are categorised using keywords such as lifestyle instead of health, fitness, or medicine. However, by targeting aspects of human or mental well-being, they do pertain to health as defined by the World Health Organization (1948).
