The convergence between mobile communication and medical devices opens new perspectives for health care. Nowadays, individuals have astonishing opportunities to monitor themselves taking accurate measurements and therefore producing myriad of data (quantified self). Moreover, the data can be shared on social media or/and with the health-care complex. This can lead to huge savings on health expenditures. However, as it is shown in the FDA Guidance on Mobile Medical Applications, the app can also bring risks, because of the low health literacy of lay people. Moreover, it can also be shown that the quantified self "ideology" considers individuals fully responsible for their health. This neoliberal fashion brackets the importance of social determinants of health.
