Postpartum depression app
A postpartum depression app for when logging is the last thing you can do
The weeks and months after birth bring one of the largest hormonal shifts of adult life. Postpartum depression and postpartum anxiety are common, treatable, and under-detected. Decibella is a postpartum depression app that uses voice samples to build a low-effort record of how you're doing — one you can share with a provider or partner.
Why voice postpartum
Depression narrows prosody, slows speech, and reduces vocal energy — patterns researchers have studied for decades. The postpartum period compounds this with sleep disruption and dramatic estrogen and progesterone withdrawal. Voice captures all of it, passively.
How it fits into the fourth trimester
• 30-second recording, any time of day • Optional one-tap mood check • Trends across weeks, not just single scores • A private, personal record — not a public feed
Important
Decibella does not diagnose postpartum depression or anxiety and is not a substitute for clinical care. If you are having thoughts of harming yourself or your baby, please contact emergency services or a crisis line immediately.
Frequently asked questions
- Is Decibella a screening tool for PPD?
- No. Decibella is a research app. If you are struggling after birth, please contact your provider or a perinatal mental-health service. In the US, call or text 988. In the UK, call 111 or Samaritans on 116 123.
- Why voice for postpartum mood?
- Depression affects prosody, speech rate, and vocal energy in well-documented ways. Combined with the dramatic postpartum hormonal shift, voice offers a low-effort way to track how you're doing during a period when filling out forms is nearly impossible.
- How much time does it take?
- Under a minute a day. You can record while feeding, walking, or before bed.
