Veil: White Noise Sleep Sounds

Veil is the white noise machine your phone should have been all along.

Every sound is generated in real time. No audio files. No loops. No repeats. Like a dedicated premium hardware noise machine, Veil produces truly infinite sleep sounds that never click, pop, or restart.

White, pink, and brown noise plus a fan sound are completely free. No limits.

23 SOUNDS. ALL GENERATED. NONE RECORDED.

Six noise colors, seven fan variants, eight mechanical sounds, and two kinds of rain. Every one synthesized on your device in real time.

NOISE COLORS

White noise, pink noise, and brown noise, each synthesized and filtered to precise frequency specifications. Green noise, mid-focused with the bass rolled away, so it masks without the weight of pink or brown. Grey noise, tuned to how your ears actually hear, so it sits evenly across the spectrum instead of pushing at one end. Blue noise, bright and airy, rising toward the top, for ears that find white too dull. Not recordings. Not samples. Pure, continuous sound generated on your device.

FAN SOUNDS

Seven variants: slow, medium, fast, box, ceiling, bladeless, and tower fan. The most popular sound category on dedicated hardware noise machines, synthesized with zero room noise or recording artifacts. Slow Fan is free. Six more with Premium.

MECHANICAL SOUNDS

Window AC, central AC, airplane cabin, clothes dryer, vacuum, shower, heater, and train cabin. Deep, familiar sounds that mask everything from traffic to snoring.

TUNE EVERY SOUND

Long-press any sound to open its tuning controls. Adjust cutoff frequencies, oscillation speed, tone, depth, and more. Shape white noise from bright and crisp to dark and muffled. Slow a fan down or speed it up. Make brown noise rattle-deep or smooth. Every parameter updates in real time while the sound plays.

PRECISION VOLUME

A fine-grained analog-style volume control that lets you dial in the minimum effective masking volume. Not a coarse slider.

MIX UP TO 3 SOUNDS

Layer noise colors with fan sounds or mechanical hums. Independent volume per channel. Save your favorite mixes and recall them instantly.

SLEEP TIMER

Presets or custom duration. Audio fades out gently so you never wake to sudden silence.

BEDSIDE CLOCK

A dim, readable clock for the nightstand while a sound plays. Tap the moon on the player, or let it open on its own when a sound starts while your iPhone is charging. Two faces, adjustable brightness and size. Hold anywhere to leave.

PLAYS ALL NIGHT

Works with the screen locked, in the background, until you stop it. Lock screen controls included.

WORKS OFFLINE

Every sound is generated on your device. No internet required. No streaming, no downloads, no sound packs. Works on airplanes, in hotels, anywhere.
