PCOS symptom tracker
A PCOS app and symptom tracker for cycles that don't cooperate
Polycystic ovary syndrome (PCOS) makes traditional cycle tracking frustrating — the calendar doesn't reflect what your body is doing. Decibella is a PCOS app that uses voice biomarkers to surface hormonal patterns and PCOS symptoms independently of whether you had a period this month.
Why voice works for PCOS
PCOS shifts the balance of androgens, estrogen, and progesterone. Those hormones influence vocal-cord thickness, laryngeal muscle tone, and speech patterns. A voice sample captures a snapshot of that endocrine state — no ovulation required.
What patterns you can see
• Long-term trends in pitch and vocal quality • Days where acoustic features shift together (a possible surrogate for hormonal events) • How lifestyle changes — sleep, exercise, medication — correlate with vocal patterns • A concrete record to share with your care team
For anyone tired of guessing
PCOS care often feels like a black box: symptoms change, cycles disappear, and generic period apps have nothing useful to say. Decibella is built for the roughly 1 in 10 people worldwide who need a tracker that actually reflects their physiology.
Frequently asked questions
- Can PCOS actually change my voice?
- Yes. Elevated androgens — the hormonal hallmark of PCOS — can thicken vocal folds and lower pitch. Many people with PCOS notice subtle changes in vocal quality over time; Decibella makes those changes measurable.
- I have irregular cycles. Does Decibella still work?
- Especially then. When cycles are unpredictable, voice biomarkers give you a signal that isn't dependent on knowing where you are in a cycle. Patterns emerge from the recordings themselves.
- Does it replace bloodwork?
- No. Decibella is a research app, not a diagnostic tool. Use it to spot patterns and bring richer data to your endocrinologist or gynecologist.
