Femtech refers to a range of technologies that address health needs typically associated with women’s bodies, such as maternal health, fertility, menstruation, sexual wellness, or contraception. Our talk will examine a specific popular femtech product, cycle-tracking applications, as instruments of self-surveillance. We first discuss the relationship between technology and the experience of individual temporarility. Specifically, we focus on the relationship between surveillance workplace technologies and a sense of time discipline as an internalized drive toward increased worker productivity. We then apply this framework to the analysis of cycle-tracking apps, arguing that cycle-tracking apps perpetuate the attitude that the menstruator needs to manage their cycle for the sake of reliable participation in productivity, creating a disconnect between their internal experience of the temporality of menstruation and external pressures. Our critique contributes to the existing worries surrounding femtech—namely, the understanding of cycle-tracking apps as selling a false sense of women empowerment and separating users, under the guise of science, from self-knowledge of their bodies.
