Brown & White Noise for Sleep

Lowlight is a white noise and sleep sounds app with no ads, made for the bedside, in the dark, all night. Play brown noise, rain sounds or fan noise on a black screen, set a sleep timer that fades out instead of cutting off, and fall asleep. No ads, no account, no subscription – a free app that works fully offline, no Wi-Fi needed.

WHY IT SOUNDS DIFFERENT – NO LOOPS, NO GAPS

Most sleep sound apps repeat a short recording, and you start to hear the loop. In Lowlight, the seven noise colours are generated live by the app's own audio engine, so brown noise is true brown noise with no file and no loop. Nature sounds such as ocean, rain and fire are played as random segments crossfaded together, so a recording takes hours to audibly repeat and there is no gap to wake you. Just steady sound, with no music and no voices.

WHITE NOISE MACHINE – SEVEN NOISE COLOURS

• Brown noise for sleep – deep and rounded, the one most people choose for deep sleep

• Pink noise – balanced, softer than white noise

• White noise – the classic white noise machine sound

• Green noise – calm, centred on the mid range

• Grey noise – shaped to sound even at every pitch

• Blue and violet noise – bright and airy, good for masking noise

RAIN SOUNDS, FAN NOISE & NATURE SOUNDS

• Rain sounds: soft rain, rain on a window, rain on a tent, night rain with thunder, a rolling storm

• Fan noise for sleeping: a bedroom fan and a desk fan

• Ocean waves, forest stream, campfire, wind in the trees, night wind, an open window

• A quiet cafe with no words, and a deep drone for nights when nothing else works

WHITE NOISE FOR BABY

A Baby category of baby sleep sounds: womb sounds with heartbeat, shushing (shhh), hair dryer, vacuum, soft rain and a warm brown noise. Every sound starts at a gentle level, and it runs through the night for your newborn or toddler.

BROWN NOISE FOR STUDYING AND FOCUS

A Focus category for work and study: green noise tuned to the band where speech lives, rain on a window, a cafe with no words, a desk fan and an open window. Keep it playing under a podcast, a call or a study session.

SLEEP SOUNDS MIXER

Tap any sound to add it to the mix and drag to set its level. Layer rain with brown noise, thunder with a fan, then save the mix as a named preset. A master volume and a warmth control soften the whole mix at once. Every recording is loudness-levelled, so a campfire and a rainstorm sit at the same slider position.

PLAYS ALL NIGHT

• White noise with a sleep timer and slow fade-out – the sound eases away instead of stopping dead

• Or play all night, 8 hours and beyond, until you stop it

• Add more time with one tap if you are still awake

• Plays with the screen off, from the lock screen and from the notification

• Control it from headphones, watch or car

• Quick Settings tile to play or pause your last mix without unlocking

• "Keep playing all night" setting checks Android battery optimisation for you

BLACK SCREEN MODE

The whole app is dark. While sound plays, the screen fades to a black screen so no light wakes you or your partner – tap to bring it back. Pure black for OLED.

NO ADS, OFFLINE & PRIVATE

Lowlight has no ads, no sign-up, no analytics and no subscription. It does not even request the internet permission, so it works in airplane mode and nothing can leave your phone. Your mixes and settings stay on your device.

WHO IT IS FOR
