PMDD symptom tracker
PMDD tracker app that listens instead of asking you to log
Premenstrual Dysphoric Disorder (PMDD) can flatten a week of your life every month. Decibella is a PMDD tracker app that uses short voice samples to surface the acoustic patterns tied to PMDD symptoms — mood swings, brain fog, fatigue, irritability — without asking you to fill out another form when you feel your worst.
Why voice for PMDD
PMDD isn't 'bad PMS' — it's a cyclical, hormone-triggered disorder that affects roughly 1 in 20 people who menstruate. Because symptoms peak in the late luteal phase, traditional symptom logs miss the exact moments you have the least capacity to fill them out. Estrogen and progesterone directly affect vocal-cord tissue, laryngeal muscle tension, and the neural circuits that shape prosody. That means your voice carries objective, timestamped signal that maps onto how you actually feel.
What Decibella tracks
• Acoustic features: pitch, jitter, shimmer, harmonics-to-noise ratio, speech rate • Cycle phase alignment: how voice shifts across follicular, ovulatory, luteal, and menstrual phases • Symptom correlation: pair each recording with a one-tap mood check • Personal baselines: your patterns, not a population average
How to use it during a PMDD flare
Record for 30 seconds when you wake up. That's it. Decibella handles the pattern-finding so that when the fog lifts, you have a clear map of what happened, when, and how it compared with previous cycles — the kind of data that makes conversations with clinicians dramatically more concrete.
Frequently asked questions
- Can voice really detect PMDD symptoms?
- Estrogen and progesterone influence vocal-cord tissue, breath control, and prosody. Short voice samples across your cycle can surface patterns that align with the mood, energy, and cognitive shifts characteristic of PMDD.
- How is Decibella different from a mood tracker?
- Traditional PMDD trackers rely on manual symptom logging, which is easy to forget during a bad luteal phase. A voice sample takes seconds and captures objective acoustic signals — pitch variability, jitter, speech rate — alongside how you feel.
- Is Decibella a medical device?
- No. Decibella is a research beta. It is not a diagnostic tool and does not replace advice from a clinician. If you suspect you have PMDD, please speak with a healthcare provider.
