Emm is a first-of-its-kind smart menstrual cup with integrated biosensors, connecting users to personalized insights about their cycle and health.
Using a menstrual cup can help users become more aware of their natural cycles, simply by observing subtle changes in their bodies more closely, and Emm invites users to take note of how much of the cup's capacity they're using at every change, regularity, and shifts in patterns over time. The device itself takes the form of a medical-grade silicone insert with super-thin sensors to measure menstrual flow volume and track cycle metrics.
“Menstruation is known as the fifth vital sign, but has historically been overlooked by the wearable sector, leaving millions without the data they need to understand and advocate for their own bodies,” said Jenny Button, founder and CEO of Emm. “We envision a future where menstrual health is measured and understood as comprehensively as cardiovascular or metabolic health.”
