Brown Noise for Sleep & Relax

Brown Noise transforms your environment with scientifically-designed audio that helps you sleep deeper and focus better. Unlike white or pink noise, brown noise features deeper, more powerful frequencies that effectively mask distractions and create a calming soundscape proven to enhance concentration and promote restful sleep.
The app generates high-quality brown noise synthetically on your device in real-time, ensuring seamless looping and optimal audio quality. No recordings, no interruptions, just pure, continuous sound that adapts to your needs. Background playback keeps the audio flowing even when your screen is locked or you switch to other apps, making it perfect for all-day focus sessions or overnight sleep support.
Choose from three expertly crafted sound modes tailored to different situations. Usual provides pure, unprocessed brown noise ideal for general use. Focus delivers a bass-boosted profile specifically designed to mask environmental distractions, perfect for deep work, studying, or concentration. Relax offers a softened, calming profile with reduced bass, excellent for meditation, yoga, or unwinding before sleep.
Premium features enhance your experience with unlimited playback and advanced functionality. The Focus Timer helps you stay on task with customizable sessions from twenty-five minutes to two hours, automatically starting and stopping playback. Sleep Mode provides an eight-hour auto-stop timer with an OLED-optimized black screen that displays the time while minimizing battery drain, perfect for overnight use without worry.
The app is designed for maximum efficiency and simplicity. Battery-optimized audio processing ensures you can run brown noise all night without significant power consumption. The clean interface puts playback controls at your fingertips with intuitive volume adjustment and quick access to all features. No complicated settings, no confusing menus, just straightforward functionality that works.
