NEW: Clair introduces the first noninvasive, continuous hormone tracker.

• Tracks estrogen, progesterone, LH, FSH, and PdG in real time • Uses wrist-based biosignals instead of blood draws or test strips • Confirms ovulation by detecting post-ovulation progesterone rise • Connects hormone patterns to sleep, energy, mood, and training

It brings hormone monitoring into the wearable category for the first time.
