No expensive baby monitor hardware needed. NiNi connects two Android phones over your home WiFi and gives you real-time, low-latency, completely private audio monitoring — in seconds.
Free · No ads · No extra hardware
Every feature built to give you peace of mind — simple and straightforward.
Hear what's happening in your baby's room in real time, with low latency. Peer-to-peer — audio never touches a server.
Tap to talk back to your baby and soothe them with your voice. Push-to-talk mode, ready whenever you need it.
A live waveform and threshold line let you visually track the room's noise. Silence or crying — you can tell at a glance.
Set a sensitivity threshold and get an instant vibration or sound alert the moment your baby cries or noise spikes.
After an alert, the app automatically switches to listening for a set duration so you can assess the situation before reacting.
Once paired, devices reconnect automatically every time the app is opened — no manual setup needed.
Monitoring continues uninterrupted even when the screen is off. A foreground service keeps it alive through battery optimization.
Critical baby sounds break through Do Not Disturb. You won't miss an alert just because your phone is on silent.
Audio never leaves your local network. No cloud, no servers, no third-party listening — just your two devices talking directly.
Dedicated baby monitors are expensive and single-purpose. NiNi uses Android phones you already own to deliver the same functionality — plus two-way talk — for free.
Leave one phone in the baby's room, carry the other. Both on the same WiFi — they find each other automatically.
Download once, use forever. No hidden fees, no premium walls, no paywalls.
Sound from your baby's room never reaches any server. Fully local, fully in your control.
Two phones, one WiFi — that's all it takes. No setup, no account, no monthly fee.
