Crying percentage feature

I hate this feature! It’s so frustrating when I want to know why my baby is crying but all I get is his crying percentage and it happens a lot too!!

Pointless

What a stupid app, it basically tells me to self diagnose why my baby is crying. The recording time barely gives you enough time to record my baby crying and then says were we right, then tells me to diagnose it. What a pointless false advertising app.

FAQ

What does ChatterBaby do?

ChatterBaby analyzes your baby's cries by comparing them to a large database of infant sounds. It uses mathematical algorithms to determine potential reasons for the crying, such as hunger, fussiness, or pain.

How accurate is ChatterBaby?

The app is reported to be roughly 85% accurate in identifying pain cries and about 90% accurate for general baby cries. Fussy or whiny cries are noted as the most commonly mistaken cry types.

Is ChatterBaby a medical device and is there a cost?

No, ChatterBaby is not a medical device and should not replace parental intuition. The app is currently offered for free.

How can I ensure ChatterBaby works best?

To improve accuracy, it's recommended to use the app in an environment with minimal background noise. Avoid feeding the app soundclips of singing to your baby or other noises like a dog barking, as this can interfere with the analysis.

What happens to my baby's data?

Data is stored on a HIPAA-compliant server for scientific research, with efforts made to anonymize information. The data is used to study whether abnormal infant vocalization patterns can predict neurodevelopmental delays.
