15 sleep sounds, endless combinations

White, pink or brown noise — which is best for sleep?
All three are steady, “colored” noise that can help mask sudden sounds like traffic, a snoring partner or neighbors. The difference is how the sound energy is spread:
White noise
Equal energy across all frequencies. Bright and hissy, like TV static. Great for masking voices.
Pink noise
Softer highs, more balanced. Sounds like steady rain or wind. A popular middle ground.
Brown noise
Deep and rumbly, like a distant waterfall or the inside of a plane. Many people find it the most soothing.
There's no single “best” noise — try each for a night or two, or blend a little brown noise under rain for warmth.
Ready-made sleep mixes
Not sure where to start? Tap one of the built-in mixes: Rainy Night (rain, thunder, brown noise), Ocean Drift, Cozy Cabin (campfire and rain), Forest Stream, Deep Calm and Fan Room. Adjust any of them and save it as your own.
Sleep timer with a gentle fade
Set a timer from 5 minutes to 2 hours. During the last 30 seconds the sound fades out slowly, so the silence doesn't wake you. Prefer sound all night? Just don't set a timer.
FAQ
Do the sleep sounds work offline?
Yes. All sleep sounds and noise colors are built into the app, so they work in airplane mode with no internet connection.
Will the sound keep playing when I lock my phone?
Yes. Sounds keep playing in the background with the screen off, and you can pause from the Lock Screen or Control Center.
Can I play a sleep sound and music at the same time?
Yes. You can layer a sound mix under night piano or a bedtime story — for example soft rain under Clair de Lune.
Is brown noise better than white noise for sleep?
It depends on the person. Brown noise is deeper and many people find it more relaxing; white noise is brighter and better at masking voices. Try both in Sleep Deeper and see which you prefer.
