Brown Noise: Sleep & Focus is a calm, focused ambient sound player. Tap once to play deep brown noise — or pick white noise, pink noise, rain, ocean, forest, fan, or fireplace — set a sleep timer, and put the phone face-down. FEATURES • Eight ambient sounds — brown, white, pink noise plus rain, ocean, forest, fan, and fireplace • Seamless looping — every sound repeats continuously without a gap or click • Lock-screen controls — pause and resume from the notification shade without unlocking • Sleep timer — cycle 15, 30, 45, or 60 minutes; audio fades out over 30 seconds • Volume slider — fine-tune the level for headphones or a bedroom speaker • Warm, minimal interface — dark amber palette built for nighttime use, not daytime tech • No account or sign-up — sound plays entirely on-device, no profile required USE CASES • Falling asleep with a steady wall of low-frequency brown noise • Masking household sound, traffic, or office chatter during focused work • Studying or reading with calm rain, fireplace, or forest ambience • Steady white noise as a household masking layer • Light sleepers who wake to small sounds and want a continuous mask through the night NOISE COLOURS, EXPLAINED Brown noise has stronger low frequencies — a deep, rumbling sound many listeners find soothing for sleep. White noise is balanced across the spectrum and is good for masking sudden noises. Pink noise sits between the two and is often used for relaxation and concentration. WHAT MAKES THIS APP DIFFERENT • A sleep timer that lives on the player screen — no digging into menus • A warm, dark interface tuned for nighttime — no bright photographic backgrounds or moon-and-stars clichés • No subscriptions and no paywalls — every sound plays without sign-up PRIVACY The app uses Firebase Analytics, Firebase Crashlytics, Firebase Remote Config, and Google AdMob for telemetry and ad serving. Sound playback itself is fully on-device. There is no account, no profile, and no audio recording. A simple ambient player. Open it, tap a sound, set a timer, sleep.
