Lull: Sleep Sounds

Mix rain, ocean and white noise into your own sleep soundscape. 100% offline, private, and a one-time purchase - no subscription, no ads.

Lull turns rain, ocean waves, wind and pure noise into a soundscape you mix yourself — the calm, private way to fall asleep, focus, or block out the world.

Everything plays on your device, fully offline. There's no streaming and nothing ever leaves your iPhone or iPad: no account, no tracking, no ads, no network. It keeps playing with the screen locked, and a sleep timer fades it out gently so it won't play all night.

MIX YOUR OWN SOUND

• Layer rain, ocean, wind, a stream, a fan and white / pink / brown / blue noise
• Fine-tune each layer's volume for the exact blend that sends you off
• Save your favorite mixes and bring them back with one tap

SLEEP & FOCUS

• Sleep timer with a smooth fade-out
• Lock-screen and background playback with play / pause controls
• A calm full-screen night clock for the nightstand (great on iPad)

PRIVATE BY DESIGN

• 100% offline - works in airplane mode, on a plane, anywhere
• No account, no sign-in, no data collection - nothing leaves your device
• Localized in 9 languages

FAIR PRICE Sleep apps love subscriptions. This one doesn't. A single one-time purchase unlocks multi-layer mixing, the full sound library, saved mixes and longer timers - forever. No subscription, ever.
