Baby Pain Detection · On-Device
Naps0 detects when your baby cries in pain and alerts you immediately. For hunger, discomfort and tiredness, it gives you pattern-based guidance — useful, though with higher individual variability. Everything runs on your phone. No cloud, no data upload, no subscription.

For caregivers
Crying is your baby's only way to communicate. Science draws a clear line between pain and other cries — pain engages neurological pathways shared across all mammals, making it acoustically distinct. The other three categories are pattern-based orientations, not deterministic classifications.
Immediate priority alert. Pain cry activates primitive neurological pathways — producing elevated pitch, sudden bursts and non-linear vocal phenomena. This distinction holds across species and across individual babies. Naps0 treats this as its primary signal.
A rhythmic, repetitive cry with regular pauses may indicate hunger. Naps0 detects this acoustic pattern and suggests it as a possibility — always worth checking alongside your baby's feeding schedule.
An irregular cry with tonal variations may signal physical discomfort — gas, posture, clothing or temperature. The app surfaces this possibility for you to investigate alongside other physical cues from your baby.
A softer cry with a descending pitch contour, often paired with visual tiredness cues, may indicate the need for rest. Naps0 detects this tonal pattern as a possible indicator — combined with your own observation it becomes most useful.
Hunger, discomfort and tired signals are orientations, not diagnoses. Individual variation between babies is high. The app is a tool to reduce uncertainty — your intuition as a caregiver remains essential.
