Designed by women, for women, Clair is the first continuous hormone tracker designed to offer non-invasive, real-time health insights.
For most women seeking insights into their hormonal health, the options have been uncomfortable and inconvenient—either pricking their finger for at-home tests or scheduling appointments to have blood drawn at a clinic. As a wrist-worn wearable, Clair turns tracking estrogen and progesterone patterns via biosensors into routine self-knowledge, not a medical ordeal.
Clair has four main uses: fertility tracking so that users can get notified before their fertile window opens; hormonal health management to indicate how hormones impact everything from mood and energy to sleep quality; athletic performance to accommodate natural fluctuations during a cycle; and perimenopause and menopause support.
