About this app

Little Napper is a free baby sleep sounds app: white noise, womb sounds, heartbeat, shushing, rain and lullabies that loop all night, with a sleep timer that fades out gently instead of cutting off. A sound machine for newborns and babies that lives on your phone and works offline.

31 SOOTHING SOUNDS, ALL BUILT IN
• Newborn: heartbeat, womb, shush
• Noise: white, pink and brown noise
• Lullabies: music box, piano and gentle melodies
• Nature: rain, ocean, waves, waterfall, forest, birds, crickets, wind, fire
• Home: fan, hairdryer, washing machine, fridge, air conditioning, clock
• Travel: car, train, airplane
Every sound is inside the app. Nothing to download, no internet needed.

MADE FOR 3 A.M.
• One tap plays. No menus, no sign-in.
• Dark by default, so the screen never lights up the room. Light theme if you prefer it.
• The screen dims while Now Playing is open.
• Keeps playing with the screen off and when you switch apps.

A TIMER THAT DOESN'T STARTLE
• Presets from 15 to 90 minutes, or all night.
• Fade-out: the volume lowers gently before the timer ends, so the sudden silence doesn't wake your baby.
• Play, pause and stop from the notification and the lock screen.

YOUR OWN VOICE
• Record your shush, hum or lullaby and play it like any other sound.
• Favourites at the top of the screen for the sounds that work for your baby.

FREE, AND SAFE VOLUME BY DESIGN
Little Napper is free, with no subscription and no locked sounds, supported by a small banner. Nothing interrupts a sound once it is playing. Follows the AAP guidance for infant sleep sound: keep the phone at least 7 feet (2 m) from the crib and the level at or below 50 dB.

Tip: babies settle fastest with a low, steady volume, started before they are fully asleep.

What’s new

Bedtime reminder: one gentle notification at the time you choose, skipped when a sound is already playing (off by default, Settings). The home-screen widget now remembers your last sound, so one tap starts it even after a restart. We only ask for a rating the morning after a timer finished on its own. Smaller download.
