A MUST have

I'm a very light sleeper and I already love this! I have this playing on my bedside speaker and I can hear the difference between this and other similar App Store offerings. This is superior!

Calm Alternative

The same day my 7 day trial ended I had my finger on the button to pay another $50 for pink noise. Luckily this came thru on Reddit and I tried it out. Absolutely what I wanted that even Apple Music couldn't provide. Really simple private app. Loving it!

Amazing app!

Been a bad sleeper forever and this is the first app that actually helped. The pink noise setting is perfect. So glad my friend told me about this!

I have been using Apple Music for pink noise. This app is so simple, so cheap, and so what I wanted. Thank you!

New: Noise Tuning

Shape every sound
to fit your ears.

No two people hear noise the same way. Veil lets you tune each sound with precision controls: adjust the treble blend, set the low-pass cutoff frequency, change the speed, and set the level. Make brown noise deeper. Make pink noise brighter. Dial in exactly what works for you.

No other white noise app gives you this level of control. Most don't even let you adjust a single parameter. Veil gives you four per sound.

The Science of Sound

Not all noise
is equal.

Each color of noise has a different frequency character, and each one affects focus and sleep differently. A little context goes a long way toward finding what actually works for you.

White Noise
Equal energy,
every frequency.

White noise distributes equal power across all frequencies, like all colors of light blended together into white. The result is a bright, dense hiss that forms a consistent wall of sound, blocking out sudden or shifting noises before they register.

Sounds like
TV static  ·  A rushing shower  ·  An untuned radio
Best for
Blocking sharp, unpredictable sounds like voices, traffic, or a snoring partner.
Pink Noise
Balanced power,
natural character.

Pink noise reduces power as frequency goes up, matching the natural acoustic distribution of sounds in the world around us. Warmer and softer than white noise, it's the most studied color for sleep, with research linking it to deeper slow-wave sleep and improved memory consolidation.

Sounds like
Gentle rain  ·  Wind through leaves  ·  A distant waterfall
Best for
Sustained focus and deep sleep. Not sure where to start? Start here.
Brown Noise
Deep rumble,
low and powerful.

Brown noise (named after Brownian motion, not the color) concentrates energy at the lowest frequencies, producing a deep, enveloping rumble. It's the darkest and most immersive of the three. A lot of people with busy minds swear by it.

Sounds like
Rolling thunder  ·  A powerful waterfall  ·  A jet engine from far away
Best for
Quieting a busy mind. If white noise feels too sharp or bright, try this first.

Why Veil

The hardware experience.
Without the hardware price.

Dedicated hardware noise machines cost $50–80 and do one thing well: generate non-looping noise. Veil does exactly that, on a phone you already own, for $4.99 one time.

Truly infinite sound
Every sound is synthesized in real time from white noise and digital filters. There is no audio file. There is no loop boundary. You will never hear it repeat.
Precision volume
Most apps give you a coarse 10-step slider. Veil gives you analog-style continuous control so you can dial in the minimum effective masking volume. Not just "loud enough." Actually right.
Tune every sound
Adjust treble blend, low-pass cutoff, speed, and level on every noise color. No other app lets you shape white, pink, or brown noise to this degree. Your ears are unique. Your sound should be too.
Deep fan library
Fan sounds are the most-used sounds on hardware machines. Veil includes five synthesized variants: slow, medium, fast, box, and ceiling. Each one has its own tonal character, so you can find the one that actually clicks for you.
Designed for the dark
Dark mode only. Large tap targets. No onboarding. No account. Playing in under two taps from install. Usable with one eye open.
Mix, save, and recall
Layer up to three sounds with independent volume controls. When you find the combination that works, save it as a named mix. One tap to restore it next time.
Voice control
Ask Siri to play Brown Noise or stop Veil without unlocking your phone. Hey Google shortcuts on Android. Works from lock screen, earbuds, and HomePod.
Timer that fades
Set a sleep timer from 15 seconds to 8 hours. When time is up, the audio fades out gradually — no abrupt silence that jolts you awake. The way a hardware machine should have always worked.
Made yours
Customize the animated waveform visualizer style. Set your own time-of-day greeting so the app says something that feels like yours, not a generic good morning from a template.

How it stacks up

Hardware quality.
App store price.

Ask any user of the major white noise apps and you'll hear the same complaint: the loop restarts. Some of those apps charge $60 a year. Veil doesn't loop. Full stop.

Questions

Things people
want to know.

When audio loops, there is a seam. The point where the file ends and starts again. At night, your brain is primed to detect patterns, even subtle ones, and that boundary registers as a cognitive event, enough to pull you out of light sleep or break your focus. Generated noise has no seam because there is no file. Every second is unique. Nothing to repeat.
More than you would expect. The reviews for most major white noise apps include at least one complaint about the loop restarting. Short loops under 60 seconds are almost universally audible after a few nights. Longer loops are harder to consciously detect, but the repeating pattern is still processed by your brain. Some of those apps charge $60 a year for the privilege. Veil sidesteps the problem entirely.
White noise is equal energy across all frequencies. Bright and dense, like TV static. Pink noise rolls off as frequency goes up, matching how natural sounds are distributed. Warmer and softer, like steady rainfall. Brown noise concentrates energy in the bass. Deep and enveloping, like distant thunder or a large waterfall. Most people find pink the most natural starting point. Brown is popular with anyone who finds white too harsh or wants to quiet a busy mind. Read our full comparison.
Yes. Background audio through screen lock is a hard requirement for a sleep app, and Veil treats it as non-negotiable. Audio continues through screen lock, app backgrounding, and notification interruptions on both iOS and Android. Lock screen controls (play, pause, stop) are fully supported.
Because Veil generates noise. That is the whole product. There is no content to maintain, no streaming costs, no service to bill you for. A one-time price is the honest pricing model for a utility. Unlock it once, it is yours on every device you own, forever, no annual renewal required.
No. And that is actually an advantage. Real fan recordings contain room noise, microphone artifacts, and a physical loop point. Synthesized fan sounds model the mechanical characteristics of each fan type mathematically: blade shape, motor speed, housing resonance. The result is cleaner, warmer, and never loops. Synthesized beats recorded every time.
Yes. On iOS, Veil integrates with Siri Shortcuts so you can say things like "Hey Siri, play Brown Noise" or "Hey Siri, stop Veil" without touching your phone. On Android, Hey Google shortcuts work the same way. Both are available to Premium users and work from your lock screen, earbuds, and HomePod or smart speaker.
Yes. Premium users can save any mix of up to three sounds — with individual volume levels — as a named preset. Your saved mixes appear at the top of the home screen alongside the individual sounds, so restoring your go-to combination is always one tap away.
Yes. Every sound in Veil has tuning controls that let you shape it to your preference. For noise colors you can adjust treble blend, cutoff frequency, speed, and level. For fans and mechanical sounds you can control tone, oscillation, and motor characteristics. Want brown noise that is deeper and heavier? Lower the cutoff. Want a fan with a slower pulse? Drag the oscillation speed down. These controls give you a level of precision that no other white noise app offers, so you can dial in exactly what your ears need.
Yes. Veil supports AirPlay, so you can stream to a HomePod, Apple TV, or any AirPlay-enabled speaker. It also works with any Bluetooth speaker or headphones. A lot of people use Veil through a bedside Bluetooth speaker for louder, room-filling sound, which is one of the advantages over a dedicated noise machine that is limited to its own built-in speaker.
Yes. Every sound is generated on your device in real time. There is nothing to stream and nothing to download. Veil works on airplanes, in rural areas, underground, or anywhere with no cell signal. It does not need Wi-Fi, mobile data, or any network connection to function.
Veil has 14 procedurally generated sounds across three categories. Noise colors: white noise, pink noise, and brown noise. Fan sounds: slow fan, medium fan, fast fan, box fan, and ceiling fan. Mechanical sounds: window AC, central AC, airplane cabin, clothes dryer, vacuum cleaner, and shower. White noise, pink noise, brown noise, and slow fan are free. Premium unlocks all 14.
At a reasonable volume, yes. Sleep researchers generally recommend keeping noise at or below 50 decibels, roughly the level of a quiet conversation. Veil includes a precision volume control designed to help you find the minimum effective masking level, rather than just cranking the volume. The built-in sleep timer can also fade the audio out after you fall asleep if you prefer not to run it all night.
Veil is designed to run all night with minimal battery impact. Because it generates sound locally instead of streaming audio, there is no network activity keeping your radios awake. The screen stays off, and the audio engine runs efficiently in the background. Most users report 5 to 10 percent battery drain over a full eight-hour night.
Absolutely. Many people use Veil during the day for concentration. Brown noise is especially popular for focus and deep work because its low-frequency emphasis masks distracting speech and office noise without adding harsh high-frequency content. Pink noise is another strong choice for sustained attention. The sound tuning controls let you dial in exactly the right balance for your environment. Learn more about brown noise for focus.
