Description by 婉 唐(from the App Store)
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 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 with one tap tomorrow night.
SCENE WORLD — STEP INSIDE THE SOUND Five fully animated worlds that respond to the sounds you play. Each scene is a living environment, not a static wallpaper. • Campfire — crackling fire under a pine-forest sky, crickets and a cool stream (free) • Aurora — shimmering northern lights over an arctic sea, perfect with ocean waves • Rainy Night — a purple city in the rain; choose drizzle, rain, downpour or thunderstorm • Snowy Night — falling snow, chimney smoke and warm cabin windows • Firefly Night — a summer meadow, frogs on lily pads and drifting fireflies
SLEEP TIMER WITH GENTLE FADE-OUT Set 5 minutes to several hours. With Fade Out on, the volume lowers slowly before stopping — no jarring silence to wake you.
SLEEP CYCLE CALCULATOR Tell Lull when you need to wake up and it suggests the ideal bedtime, working backwards through 90-minute sleep cycles.
MADE FOR THE DARK A true night-first interface: deep dark theme, no blinding whites, no fuss. Tap play and put the phone down.
WIDGETS INCLUDED Start and stop playback from the Lock Screen or Home Screen without unlocking your phone.
MADE FOR IPHONE AND IPAD A layout designed for iPad, not a stretched phone app. Home, the sound library and the mixer are all rearranged for the bigger screen, in portrait, landscape or Split View. Buy Premium once and restore it on your iPhone and iPad with the same Apple ID.
