How it helps

Breathe. Naps0 is listening.

It flags what matters most, first

If the cry suggests intense distress, Naps0 gives you a priority heads-up so you can react sooner. The rest of the needs — hunger, sleep, discomfort — it shows as guidance.

Calmer when you don't know what's wrong

When your baby cries and you don't know what's wrong, Naps0 gives you a hint of what they might need. So you respond with more confidence and less worry.

It works while you rest

Naps0 listens in the background and alerts you as soon as it recognizes a cry. You don't have to watch the screen: you rest, the app stays attentive.

Made for first-time parents

No complicated setup, no jargon. You open it, it listens, it alerts you. For those nights that get tough.

Privacy

The most intimate sound in your home shouldn't travel to any server.

With Naps0, everything happens inside your phone. Your baby's cry is processed right there, on your device, and the audio never leaves the phone.

Unlike apps that send the sound to the cloud, with Naps0 your baby's voice stays where it belongs: with you.

FAQ

Questions parents ask

How does Naps0 work?
It listens to your baby's cry and, in real time, helps you understand what they might need: hunger, sleep, discomfort or pain. If the cry suggests intense distress, it gives you a priority heads-up. All the analysis happens inside your phone.
Does Naps0 diagnose whether something is wrong with my baby?
No. Naps0 is a help to understand your baby better, not a diagnosis and not a substitute for your pediatrician. It gives you a hint of what they might need, but it doesn't detect illnesses and doesn't replace a professional's judgment. For any health concern, always check with your pediatrician.
Is my baby's audio stored or uploaded anywhere?
No. Everything is processed on your own phone and the audio never leaves it. No cloud, no servers, no accounts. It even works without an internet connection.
Will I be charged when the 10 days end?
No. The 10 days are free, no card. When the trial ends nothing is charged automatically. If you want to keep using Naps0, you make a single payment yourself. It's not a subscription and there are no automatic charges.
Is it really a one-time payment, or do more charges come later?
It's a single payment. Just once. No fees, no renewals and no extra purchases inside the app: that payment unlocks everything.
What age is it for?
It's made for your baby's first year, when crying is their main way of communicating (optimized for the first 0-9 months). Outside that window it may be less reliable.
Do I need to buy any extra device or gadget?
No. All you need is your Android phone. No cameras, no wristbands, no extra sensors.
What if it doesn't always get it right?
Naps0 is one more help, not a certainty. It gives you guidance on what your baby might need so you can decide with more information, alongside your own instinct. You're still the one who knows your baby best.
