Lull: White Noise Sleep Sounds — App Store rankings

About this app

The developer's US App Store description, in full.

Fall asleep faster. Soothe your baby. Breathe deeply. Focus without distraction. Lull plays the perfect ambient sound for every moment — and never cuts out mid-night, never shows an ad, never asks for a subscription. ——— WHY LULL IS DIFFERENT ——— Most sleep sound apps fail the moment you need them most. Ads blare through naptime. Audio stops after 20 minutes. A $70/year subscription just to hear rain. Lull is the answer: try everything free for 7 days, then one small purchase — never a subscription. Sounds that never cut out mid-night, and a mixer that makes it yours. ——— THE SOUND MIXER ——— Layer up to 6 sounds simultaneously with individual volume sliders. Brown noise at 70% with gentle rain at 40%? Done. Save it as a mix. Resume it tomorrow night with one tap. ——— 50 SOUNDS ACROSS 5 CATEGORIES ——— • Noise — White, pink, brown, green, and blue noise — algorithmically generated so they never loop, never repeat, never have that telltale seam at 2am • Nature — Rain, ocean, thunder, crickets, birds, wind • Urban — Fan, HVAC, coffee shop, train • Baby — Heartbeat, womb, shushing, and more • Weather — Storms, drizzle, rain on leaves ——— CURATED MIXES — GREAT FROM DAY ONE ——— • Deep Sleep — Brown noise + gentle rain • Rainy Night — Layered rain for restless nights • Baby Calm — Heartbeat + womb sounds • Soft Pink — Pink noise, clean and natural • White Focus — White noise for sharp concentration ——— CALM & BREATHE ——— Step away from the noise. Lull's Calm category has 41 sounds designed for relaxation, breathwork, and unwinding — soft rain, deep forest, gentle ocean, and more. ——— SLEEP TIMER & GENTLE FADE ——— Set a timer: 30 minutes, 1 hour, all night. Lull fades out gradually so you never jolt awake. Set a bedtime reminder and let your routine take care of itself. ——— PLAYS ALL NIGHT, EVERY NIGHT ——— Proper background audio — Lull keeps playing when you lock your screen, switch apps, or get a phone call. No cutoffs. No timeouts. No silence at 3am. ——— FULLY OFFLINE ——— All sounds are stored on-device. No streaming. No Wi-Fi required. Works anywhere — cabin, plane, hotel room. ——— LOCK SCREEN CONTROLS ——— Start, stop, and switch sounds from the lock screen. Perfect for parents with a baby in their arms who cannot unlock a phone. ——— 7 DAYS FREE, THEN ONE PURCHASE. NO SUBSCRIPTION. EVER. ——— Every sound is unlocked free for 7 days. After that, unlock Lull once for $5.99 and keep it forever. No renewal. No surprise charge. No "plan" to manage. Just sound, the way it should be.
