Hormone tracker app

A hormone tracker app built on your voice

Estrogen, progesterone, and androgens shape mood, energy, cognition — and your voice. Decibella is a hormone tracker app for women's health that turns short daily recordings into a personal map of hormonal patterns across cycles, PCOS, perimenopause, and the postpartum period.

One signal, many conditions

The same underlying hormones drive PMDD, PCOS, endometriosis flares, postpartum mood shifts, and perimenopausal changes. Voice biomarkers give you a single, consistent measurement that stays useful as your body and stage of life change.

What you can do with it

• Track hormonal patterns without daily manual logging • Notice how sleep, stress, and medication interact with your cycle • Bring an objective record to appointments • Contribute to research building better tools for women's health

Beta and research-first

Decibella is in research beta. It is not a diagnostic tool. It is built with, and for, people who have been under-served by mainstream health tech — and who deserve tools that reflect how their bodies actually work.

Frequently asked questions

What hormonal conditions can Decibella help with?
Decibella is being studied across PMDD, PCOS, endometriosis, postpartum depression, perimenopause, and general cycle tracking. Any condition tied to estrogen, progesterone, or androgen shifts is in scope.
How is this different from Flo or Clue?
Period trackers rely on calendar inputs and manual symptom logs. Decibella adds an objective, physiological signal — your voice — that reflects hormonal state directly, even when cycles are irregular or absent.
Do I have to have a regular cycle?
No. Voice biomarkers work independently of cycle regularity, which makes Decibella useful across PCOS, perimenopause, postpartum, and hormonal therapies.
