Lull - Sleep Sounds Android

Lull - Sleep Sounds

Mix sleep sounds, white noise & ambient audio. Sleep timer. Buy once.

Features & Capabilities

Lull is an ambient sound mixer for sleep, focus, and meditation. Mix sleep sounds, white noise, brainwave tones, and ambient soundscapes until it feels right. Layer up to eight sounds at once, with independent volume on every track.

Most sleep apps give you pre-made tracks. Lull lets you build your own.

SOUNDS

Over forty ambient sources across seven categories:

• Nature — ocean waves, gusting wind, small stream, forest rain, heavy rain, distant thunderstorm, rumbling thunder
• Indoor — campfire, ticking clock
• Urban — coffee shop, train cabin, downtown street, distant traffic
• ASMR — breathy whispers, brushing, page turning
• Noise — brown, velvet, orange, pink, white, blue, violet, gray, green
• Brainwaves — six isochronal tones, from Delta (2 Hz, deep sleep) to Gamma (40 Hz, clarity)
• Frequencies — ten solfeggio tones, 174 Hz to 963 Hz

FEATURES

• Layer up to 8 sounds at once
• Independent volume on every track
• Sleep timer with a gentle fade to silence
• Bedtime reminders — local notifications, no servers
• Save your favorite mixes for one-tap recall
• Curated starter mixes: Deep Sleep, Rainy Night, Mountain, Ocean
• Background playback and lock-screen controls
• Works fully offline — no internet required

ONE PURCHASE, FOREVER YOURS

A one-time purchase. No subscriptions, no ads, no tracking. No account required. Your saved mixes, bedtime, and timer preferences stay on your device. If you get a new phone, re-download from Google Play and you own it again — no "restore purchase" button needed.

GOOD FOR

• Falling asleep when your mind won't quiet down
• Focus and deep work
• Meditation and breathwork
• Travel and noisy environments
• Calming infants and pets
• Drowning out neighbors, traffic, conversations

A NOTE ON BRAINWAVES & FREQUENCIES

The brainwave and solfeggio sounds are tools people have used for relaxation, focus, or sleep — not medical claims. Lull is built for experimentation. Find the combination that works for you.

Built for the moments between things. The half-hour before sleep. The work session that needs to start. The quiet you can't quite find.
