Problem
Women often need to use multiple separate tools—calendar apps for cycle tracking, at‑home hormone test kits, and fitness wearables—to monitor hormonal health, fertility, training, and menopause symptoms. This fragmented approach leads to incomplete data, inaccurate predictions, and extra effort, especially for those with irregular cycles.
Solution
Clair offers a single wearable device and companion app that continuously estimates key female hormones (estrogen, progesterone, LH, FSH) by analyzing over 130 physiological biomarkers captured through a multi‑modal sensor array. Machine‑learning models, trained on clinical‑grade hormone measurements, translate these signals into real‑time hormone levels, cycle phase classification, and fertile‑window predictions. The platform provides personalized insights for training, recovery, fertility planning, and perimenopause management, all processed on‑device to keep data private. Users receive intuitive visualizations, performance zone recommendations, and the ability to share relevant insights with partners, enabling proactive health decisions without invasive testing.
Target Audience
Primary users are women seeking integrated hormonal health monitoring for fitness, fertility, or menopause management, including athletes, health‑conscious individuals, and those with irregular cycles.
