Brown noise. Nothing else.

Brown noise. Nothing else.

A calm, focused app that does one thing beautifully: play deep, steady brown noise for sleep, focus and relaxation.

NO LOOPS. EVER.
Most noise apps repeat a short audio file over and over. Brown Noise generates sound live on your iPhone, sample by sample, so there's no seam, no repeat and nothing to download.

A SLEEP TIMER THAT FADES
Set a timer and the sound fades out gently over the last minutes, so it never wakes you up.

FIND YOUR SOUND
- Brown – warm and steady, great for focus
- Deep – an ultra-low rumble for sleep
