Lull Sleep Sounds: good sleep

Sleep better tonight with Lull. Mix calming sleep sounds, set a sleep timer, and drift off as Lull fades everything out. Set a bedtime once, and every night your sounds start on their own, even with your phone locked.

SLEEP SOUNDS THAT NEVER LOOP
Lull's sounds are created live on your phone, so there's no audible loop, no seam and no repeat. Rain sounds stay rain all night. Nothing is downloaded, so the app is tiny and works fully offline.

• Nature: rain, heavy rain, rain on a tent, thunderstorm, ocean waves, wind, a babbling stream, waterfall, campfire, a night forest
• White noise and more: white noise, pink noise, brown noise, fan noise, airplane cabin, a slow heartbeat
• Sleep music that never repeats: soft piano, music-box lullabies, warm pads, wind chimes, singing bowls, kalimba, deep space

MIX YOUR PERFECT NIGHT
Tap sounds to layer them, then set each volume. Every sound is balanced to the same loudness, so adding rain to brown noise never jumps out. Save the mixes you love, or start with one made for you: Rainy Piano, Cozy Cabin, Seaside Fire, Stormy Coast and more.

A SLEEP TIMER THAT FADES GENTLY
Choose 15 minutes to 8 hours. As the timer ends, Lull fades your sounds out slowly, so the silence doesn't wake you. Add 15 minutes from the notification or your lock screen.

BEDTIME ON AUTOPILOT
Build a calm bedtime routine without touching your phone. Pick a time and the days, like weeknights at 10:30 PM. At bedtime Lull fades your mix in by itself, plays it for as long as you choose, then fades out and stops. Tap "Test in 1 minute" to check it on your phone.

FALL ASLEEP TO YOUR OWN SONGS
Add songs from your phone and play them with your sleep sounds, looped or shuffled. You choose the files in Android's own file picker, so Lull never needs access to your storage. Songs are matched in volume to Lull's sounds and fade out with the timer.

MADE FOR THE BEDROOM
• A dark, gentle design that's easy on tired eyes
• Lock-screen, headphone and Bluetooth controls
• Pauses when your headphones disconnect, and for phone calls
