Lull - Sleep Sounds

Sleep sounds, mixed your way

$1.99 · Designed for iPad. Not verified for macOS.

40+ sounds. Stack up to 8. Sleep timer that fades. Bedtime reminders. One purchase, yours forever — no subscriptions, no ads, no tracking. Lull is an ambient sound mixer built for drifting off, finding focus, or just slowing down. Pick a few sounds. Slide each volume until it feels right. Let it carry you. Most sleep apps give you pre-made tracks. Lull lets you build your own — layering up to eight sounds at once, each with independent volume control. WHAT'S INSIDE 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 with independent volumes • Sleep timer with a gentle fade to silence • Bedtime reminders — local notifications, no servers • Save your mixes — they appear on the home screen for one-tap recall • Curated starter mixes: Deep Sleep, Rainy Night, Mountain, Ocean • Background playback and lock screen controls • Works fully offline ONE PURCHASE, FOREVER YOURS $4.99, one time. Every sound, every feature. No subscriptions, no ads, no tracking. No account required. Your saved mixes, bedtime, and timer preferences stay on your device. A note on the brainwave and frequency categories: these are sounds people have used for relaxation, focus, or sleep — they aren't 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. Drift off.
