Hormometer™
The world’s first instant hormone monitoring system.
WHY HORMONES MATTER
Hormones impact your entire body—and they fluctuate constantly.
Hour by hour. Day by day. Month by month. These fluctuations impact how you show up. Understanding them unlocks how you perform.
By tracking your hormonal data over time, you can spot trends and see the big picture—detecting problems before they develop and making adjustments to perform your best.

SCIENCE OF SALIVA
Saliva isn’t new. Decoding it in real-time is new.
Saliva levels mirror blood levels.
Saliva is complex, carrying over 1000 measurable biomarkers at microscopic levels. It only carries bioavailable (unbound) hormones, meaning the building blocks your body actually uses.

Hormone levels in saliva are 1000x more difficult to detect than in blood.
Only ultra-sensitive chemistry, precision microfluidics, and AI-driven optics made hormone levels detectable in saliva without a lab.
