Sleep Mask: Adaptive Noise

A private noise machine that adapts to your room. Mask snoring, traffic, and voices with synthesized sound that stays entirely on your device. Most sleep sound apps play a recording. Sleep Mask creates noise in real time and can adapt it to the sounds around you. Turn on Adaptive Masking and Sleep Mask samples the room continuously. It analyzes that moment entirely on your iPhone, then adjusts its synthesized sound to better cover distractions such as snoring, traffic, a television, or voices through the wall. SHAPE A SOUND YOU CAN SLEEP WITH Choose White, Pink, Warm Pink, Brown, Deep Brown, or Fan noise. Then tune the tone from open and airy to soft, warm, or dark. TWO ADAPTIVE MODES • Level mode responds to the sound present in each frequency range. • Flux mode focuses on changing sounds while paying less attention to steady background hum. SEE THE ADAPTATION The live spectrum shows the room analysis, generated noise, and adaptive correction so you can see how the sound is being shaped. STAYS OUT OF YOUR WAY Set a sleep timer, choose how quickly adaptation responds, and limit the maximum boost. Audio continues when the screen locks so you can settle in without keeping the app open. PRIVATE BY DESIGN Microphone samples are processed only on your device. They are never recorded, stored, or transmitted. Sleep Mask has no account, ads, analytics, tracking, or data collection. NO SUBSCRIPTION Every feature is included. There is no recurring fee and nothing to manage in the morning.
