A study on the use of mobile health apps and human creativity. An Anthropological Approach to mHealth underlines ten sixteen-month ethnographies, set across Asia, Africa, Europe, and Latin America, that revealed people’s use of communicative apps, including as LINE, WeChat, and WhatsApp’s alternative primary health apps, highlighting the irrelevance of dedicated health apps. Using a “smart-from-below” approach, this book studies these surprising practices and proposes a radically different anthropological method to the development and dissemination of mobile health (mHealth), a rapidly growing sector in healthcare.
