Apple Watch baby monitor
MonitorBaby
Turn the Apple devices you already own into a calm, private baby monitor. Your iPhone listens near the crib, your Apple Watch stays on your wrist, and the app keeps the status readable at a glance.
Live sound
Built around the screen you actually check.
MonitorBaby keeps the interface quiet until it needs your attention: a live waveform, a clear sound level, and a simple last-sound status.

How it works
Set it down, keep your wrist free.
Watch the live status
Sound levels and detected audio stay visible on iPhone and Apple Watch.
Get tapped when it matters
Wrist alerts help you respond when crying starts, without checking constantly.
Privacy
Your baby's audio stays on your devices.
MonitorBaby is built to feel like a family tool, not a data product. It works without account setup, cloud storage, or third-party trackers.
On-device processing
Cry detection runs locally instead of sending nursery audio to the cloud.
Encrypted connection
The live session between your iPhone and Apple Watch stays private.
Made for Apple devices
Requires iOS 18.6+ and watchOS 11.6+, with Family Sharing support.
