Lull: White Noise & Deep Sleep

Lull is an ambient sound app built for one thing: helping you fall asleep, focus, or unwind — without the clutter.

62 HAND-CRAFTED AMBIENT SOUNDS
Nature, city, industrial, Lo-Fi music and binaural beats. Every sound is designed to loop seamlessly with natural variation — it never sounds like a loop.

LAYER SOUNDS IN THE MIXER
Combine rain on a roof with a coffee-shop hum and a Lo-Fi piano. Save your mix and load it with one tap tomorrow night.

SCENE WORLD — STEP INSIDE THE SOUND
Five fully animated worlds that respond to the sounds you play. Each scene is a living environment, not a static wallpaper.
• Campfire — crackling fire under a pine-forest sky, crickets and a cool stream (free)
• Aurora — shimmering northern lights over an arctic sea, perfect with ocean waves
• Rainy Night — a purple city in the rain; choose drizzle, rain, downpour or thunderstorm
• Snowy Night — falling snow, chimney smoke and warm cabin windows
• Firefly Night — a summer meadow, frogs on lily pads and drifting fireflies

SLEEP TIMER WITH GENTLE FADE-OUT
Set 5 minutes to several hours. With Fade Out on, the volume lowers slowly before stopping — no jarring silence to wake you.

SLEEP CYCLE CALCULATOR
Tell Lull when you need to wake up and it suggests the ideal bedtime, working backwards through 90-minute sleep cycles.

MADE FOR THE DARK
A true night-first interface: deep dark theme, no blinding whites, no fuss. Tap play and put the phone down.

WIDGETS INCLUDED
Start and stop playback from the Lock Screen or Home Screen without unlocking your phone.
