Big Beautiful Noise App

Big Beautiful Noise App is a quiet, focused sound machine for the night.

One screen. One carefully tuned, continuous broadband sound. Tap once to play, lock your iPhone, and let it softly mask the small noises that can interrupt a room.

The interface stays intentionally minimal: the current time, a subtle session timer, and one play/pause control. Press and hold the timer to reset it. Playback continues when your iPhone is locked, with controls available from the Lock Screen.

The sound is generated continuously on-device. There are no loops, ads, accounts, subscriptions, analytics, network requests, microphone access, or sound choices.

Big Beautiful Noise App is a sound masker, not medical treatment or a promise of better sleep. Use the lowest volume that works for your room.
