Features
Every detail, tuned for calm
Brown Noise isn't a playlist — it's a purpose-built sleep and focus tool. Here's what's inside.
Sleep
A timer that fades you to sleep
Set a duration and the sound gently fades to silence as you drift off — no jarring stop that jolts you awake at 2am. Choose a hard stop or a smooth fade-out over the last minutes.
- ✓ Custom durations up to 8 hours
- ✓ Smooth fade-out mode
- ✓ Optional gentle wake-up sound
Quality
Seamless loops, engineered from lossless audio
Cheap noise apps click every time the loop restarts. Ours are built from uncompressed audio with equal-power crossfades at matched zero-crossings, so the sound is truly continuous — even after hours.
- ✓ No clicks, pops or gaps
- ✓ Three intensities per noise color
- ✓ Tuned for −18 LUFS, easy on the ears
Control
Runs in the background, all night
Lock your phone, switch apps, or slip it under your pillow — the sound keeps going. Full controls live on the lock screen and in Control Center, just like your music app.
- ✓ Background & lock-screen playback
- ✓ Control Center integration
- ✓ Works with AirPods & any output
Anywhere
Fully offline, private and ad-free
Every sound is on your device — no streaming, no buffering, no ads, no account required to start. Perfect for flights, camping, or simply keeping your data to yourself.
- ✓ 100% offline playback
- ✓ No ads, ever
- ✓ No sign-up to start listening
Why a native app
App vs. a YouTube tab vs. a website
The difference shows up the moment your phone locks.
