"Finally, a wearable that understands women" - TechCrunch

Designed by women, for women

The Science Behind Joan

Women’s health is unique. Our cycles, hormones, and health challenges are often overlooked by mainstream solutions designed around men’s bodies.

That's why Joan is based on the science of the female cycle.

Track hormonal shifts. Understand how they impact your sleep, energy, mood, and health. Get actionable recommendations tailored to you.

Why Joan?

Frustrated by the lack of information about women's health and the existing one-size-fits-all products, we created a platform that allows you to measure and optimize your health.

Unlike traditional wearables that are based on the male-24 hour cycle, Joan is designed for women by women, prioritizing the female biological rhythm that influences your life.
