DriftNoise

DriftNoise is a tiny paid sound utility for sleep, focus, and calm. It generates white, pink, brown, fan, rain, and surf-style noise directly on your iPhone, so there is no account, no cloud library, and no internet connection required after install. Choose a sound, tune volume, warmth, and movement, then set a sleep timer with a gentle fade-out. DriftNoise keeps your last settings on device and stays intentionally simple. Core features: - Procedural white noise - Pink and brown noise - Soft fan, fine rain, and slow surf modes - Sleep and focus presets - Volume, warmth, and movement controls - Sleep timer with fade-out - Background audio playback - Local settings only - Works offline after install - No account required DriftNoise does not include medical advice and is not intended to diagnose, treat, or monitor sleep or health conditions.
