Wearable hormone tracker

Clair uses physiological signals from your wrist calibrated to urine hormone levels to calculate your hormone insights and show how they change over time. Progesterone raises your body temperature, shifts your heart rate, and alters your sleep architecture. Estrogen modulates cardiovascular tone and heart rate variability. Clair's multi-modal sensor array captures over 130 biomarkers spanning cardiovascular, thermoregulatory, autonomic, electrodermal, and other domains, then uses machine learning models trained against hormone measurements to decode the combined pattern into physiological hormonal insights.
