Brown Noise - Sleep & Focus

Brown Noise helps you sleep better and focus deeper with scientifically-backed noise colors. Choose from three noise types, adjust the volume, set a sleep timer, and let the soothing sounds do the rest. No recordings, no subscriptions, no internet required. Pure noise generated in real time on your device. NOISE TYPES - Brown Noise (Free) Deep, rumbling tones like a distant waterfall or heavy rain. Brown noise is perfect for deep sleep, concentration, and blocking out distracting sounds. Its low-frequency emphasis makes it especially soothing. - Pink Noise (Pro) Balanced, natural-sounding noise similar to steady rain or wind through trees. Research suggests pink noise may enhance deep sleep quality and memory consolidation. - White Noise (Pro) Equal intensity across all frequencies, like a fan or TV static. White noise is effective at masking a wide range of environmental sounds for both sleep and focus. SLEEP TIMER Set a timer for 15, 30, 60, or 120 minutes. The noise will gently fade out over the last 30 seconds so you are never jolted awake by sudden silence. Watch the countdown right on the main screen. BACKGROUND PLAYBACK Keep the noise playing even when you lock your phone or switch to other apps. Works with your device lock screen controls for easy play and pause. VOLUME CONTROL Simple slider to find your perfect volume level. Quiet enough for focus, loud enough to mask snoring or traffic outside your window. DESIGNED FOR NIGHT The dark, calming interface uses minimal brightness and soft accents so it will not disturb you in a dark room. FREEMIUM MODEL Brown noise and the full sleep timer are completely free. Upgrade to Pro with a one-time purchase to unlock pink and white noise types. Offline first: All noise is generated mathematically on your device. No audio files to download, no streaming, no internet required.
