Baby Pain Detection · On-Device

Naps0

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.

Understanding your baby's cry

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.

Pain
Detected · Solid evidence

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.

Hunger
Estimated · Indicative pattern

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.

Discomfort
Estimated · Indicative pattern

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.

Tired
Estimated · Indicative pattern

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.
