Mobile health smartphone applications (mHealth apps) enable patients to monitor how chronic illness interconnects with their everyday life. I explore, through focus group discussions, how such monitoring makes sense to pediatric and young patients and parents in Denmark. These groups explicate how they live both with and without chronic illness by distinguishing between when to focus on which aspects of it. I argue that this relationship with chronic illness produces parent’s, children’s, and young people’s ambivalent attitudes toward mHealth apps that promote illness monitoring “anywhere” and at “any time.”.
