Digital health services in Kenya comprise mobile health applications (mHealth apps), electronic health records, telehealth and telemedicine, which form part of an expanding digital health assemblage. These are shaped by transnational development agendas and donor-driven public health interventions. This paper discusses the for-profit turn in the digitalisation of health care – what I term the ‘appisation’ of health – as a site of intensified commodification where users are reconfigured as digitised health consumers. While other scholars have argued that digitalisation functions as extractive in deepening market penetration into spheres of life we rely on, I extend these arguments by claiming that, far from enhancing access, these technologies exploit vulnerabilities through opaque governance mechanisms and algorithmic decision-making, while transferring responsibility for health from the state to the individual, thus creating new dependencies on market-mediated platforms. Using discursive interface analysis of two health apps in Kenya, I examine how consumer health apps embed vulnerabilities while consumer law remains structurally limited in confronting the collective harms they generate.
