Wearable companies are now shifting their focus towards women’s health. Recently, a women’s health firm developed a hormone tracking device that will continuously track women’s hormones. Stanford graduates, Jenny Duan and Abhinav Aggarwal, started a women’s health firm, Clair, in 2025. The company’s first product is ready to enter the wearable industry as the first of its type.
It is a non-invasive device that measures hormonal changes and patterns in real-time. The hormone tracking device does not require any blood or urine testing; instead, it uses several physiological cues to determine the changes in hormone levels. Clair stated, “Device uses a variety of physiological cues to determine changes in important reproductive hormones, such as follicle-stimulating hormone (FSH), luteinizing hormone (LH), progesterone, and estrogen.
The Smart Wearable Designed by Women, for Women
Clair is one of the world’s first non-invasive hormone-tracking wearable especially designed for women by a team of Stanford graduates. Women remain underrepresented in the medical and research field increasing biases and generalizations in the treatments. Both the founders of the company want to bridge this gap to improve women-centered treatments and issues.
Abhinav Aggarwal, co-founder of Clair, said, “Hormone tracking can provide insight into menstrual cycle patterns and can aid with both diagnosing and assessing treatment for various conditions. Patients will have insight into their hormone fluctuation with time.”
From Fatigue to Fertility: One Bracelet Tracks It All
This smart bracelet focuses on four primary hormonal-issues faced by women, including fertility tracking, overall hormone health, support during perimenopause and menopause, and athletic performance. The company has claimed that the device will notify users before the onset of their fertility duration, as it will monitor the rise in progesterone after the ovulation period. It will also help users in gaining insights on hormones affecting their mood.
Clair’s device will also track the nocturnal rise in progesterone, identifying the cause behind constant tiredness and less energy. To maintain athletic performance and create a schedule accordingly, this device will keep track of your phases, recommending high-intensity workouts during the high-energy phase. Additionally, this bracelet will provide support and realistic information during menopause, which is often misunderstood among women.
While the company claims to completely transform traditional hormone tracking, accuracy needs to be verified by users. Many wearables enter the industry with evolutionary claims, but the important part that is often missed is accuracy.
