Soothing, science-informed sounds that help your baby drift off — and cry alerts on your phone the moment they need you.
Coming soon to the App Store for iPhoneWhite noise, shushing, heartbeat, womb sounds, a music-box lullaby, rain, ocean and more — every one generated live for perfectly smooth, all-night play. Tap any sound to see the science behind it.
Night Watch listens for crying using on-device intelligence. Audio is analyzed on your phone and instantly discarded — never recorded, never uploaded.
One phone stays in the nursery. Yours — or your partner's — gets woken the moment crying is detected. Anywhere, even with the app closed.
Gentle fade-outs, dim sensory displays, a bedside Nightstand mode, and Auto-Soothe that softly raises the sound to help baby resettle.
Automatic sleep logs: cries, quiet stretches, full night timelines, and weekly charts against age-based recommendations.
Volume capped for infant hearing safety, distance guidance built in, and honest evidence labels on every sound.
Your baby's audio is never recorded or uploaded. Sleep logs never leave your phone. The only things our servers ever see are your email and the ping that wakes your other devices. Read the full privacy policy →
