Problem
Women who need precise timing for conception, contraception, or hormonal health monitoring currently rely on daily urine tests, strip kits, or calendar-based predictions, which are prone to user error, delayed results, and limited accuracy.
Solution
Phira offers a discreet wearable earring-back that continuously measures estrogen, progesterone, and luteinizing hormone (LH) by detecting subtle vascular and thermoregulatory signals from the highly vascularized skin behind the ear. The device provides real‑time hormone data with clinical‑grade accuracy and minimal motion artifacts, enabling users to identify fertile windows, track hormonal cycles, and detect irregularities as they occur. Data are processed on‑device and synced to a companion app where users receive actionable insights for conception planning, natural contraception, and overall hormonal balance. By eliminating the need for urine strips and manual logging, Phira delivers continuous, non‑invasive monitoring that adapts to daily activities, sleep, exercise, and nutrition.
Target Audience
Phira is aimed at women of reproductive age who are trying to conceive, seeking natural contraception, or monitoring hormonal health, including individuals using fertility clinics, reproductive health practitioners, and wellness platforms.
