Lull: Sleep Sounds & Mixe

Fall asleep faster. Focus deeper. 62 handcrafted sounds you can mix endlessly. Newly redesigned — beautiful, fast, and pay once to keep forever.

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 recorded or 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 in one tap next time.

SCENE WORLD — STEP INSIDE THE SOUND

Five fully animated worlds that respond to the sounds you activate. Each scene is a living environment, not just a static wallpaper.

Campfire — Crackling fire under a pine forest sky. Crickets, embers, a cool stream nearby. (Free)

Aurora — A shimmering green aurora over an arctic horizon. Pair with ocean waves or delta binaural beats.

Rainy Night — A purple city night in the rain. Choose your intensity: drizzle, rain, downpour, or thunderstorm.

Snowy Night — Deep winter silence. Snow falling, a distant dog, the creak of a Nordic cabin.

Firefly Night — A warm summer night in the grass. Frogs on lily pads, cicadas, a gentle stream.

SLEEP TIMER WITH FADE OUT

Set a timer from 5 minutes to several hours. Turn on Fade Out and the volume drops slowly before stopping — no jarring silence to wake you back up.

SLEEP CALCULATOR

Tell Lull when you need to wake up. It works backwards through sleep cycles and suggests the ideal bedtime.

DESIGNED FOR NIGHT USE

Dark theme throughout. No blinding whites, no disruptive animations. Tap play, put the phone down.

LOCK SCREEN & HOME SCREEN WIDGETS
