## What is Noise Machine?

Fall asleep easily, focus, or relax with brown noise, green noise, pink noise, and white noise, plus an integrated sleep timer.

Features:
* High-quality white noise, pink noise, green noise, and brown noise
* Integrated Sleep Timer that fades out noise after a set time
* Mix noise with the audio from other apps
* Play on speakers, AirPods, or HomePod
* Control from the lock screen
* Relaxing Dark Mode
* Ask Siri to "Play Noise Machine” or to play a specific noise

Noise Machine is the best noise maker app! The beautiful design of this white noise maker app is a joy to use each night.

Noise Machine features four “colors” of noise - each with different properties:

• Brown Noise (also known as Red Noise) has a rich, deeper character with strong low frequencies and roars like a river or an ocean. Brown noise is beneficial for sleep, and even more effective when played through a powerful speaker to bring out its deep tones. Our brown noise is mathematically accurate, representing the true nature of brown noise.

• Green Noise has an ambient and natural feel that gives the feeling of being in a forest or river valley. Green noise is energizing like a long walk in the woods.

• Pink Noise has a more balanced texture that highlights the middle frequencies evenly, like a calming rain storm. Our pink noise is mathematically balanced.

• White Noise is pure and flat with an equal balance of low, medium, and high-frequency sound. White noise may sound like a waterfall cascading down a rocky cliff. Our white noise is mathematically accurate, representing true white noise.

Noise Machine now works with Siri. Say “Hey Siri, play Noise Machine” to pick right up where you left off with your favorite noise. You can also say:

“Hey Siri, play brown noise on Noise Machine.”

Are you often distracted by irritating sounds when trying to sleep at night, like city noise, loud traffic, the fan ticking, the neighbor’s music, or a partner snoring? Put on your sleep noise using this app, and you will soon find that distractions are no longer bothering you. You will also notice that this noise has a calming effect that helps you relax and drift off to sleep naturally. Once you have connected with the benefits of these sleep sounds, it may profoundly change the way you sleep.

These noises are also very effective in focusing the mind on office work, study, or thought in distracting environments. By replacing the base volume of the background noise in the environment around you with random white noise, pink noise, or brown noise, the distracting sounds are drowned out, leaving you a soothing virtual silence. The noise-canceling sounds replace the background noise. The calming effect of the noise helps focus the mind on the task at hand, facilitating clarity and productivity.

The audio from this app works great when played directly from your iPhone or iPad speaker and can also connect to headphones, AirPods, a Bluetooth speaker, HomePod, or other audio device for a louder and deeper bath of calming noise. Why buy a portable noise maker or sound machine when you can use the devices you already own!

Noise Machine features a sleep timer to automatically turn off noise at night after a set time. Some people like to fall asleep by relaxing with noise, but find that they prefer the noise to fade out during sleep. Set a sleep timer to your desired time, and the noise will fade out very slowly.

People use Noise Machine to:
• fall asleep faster
• block out distracting sounds
• provide a source of background noise
• increase focus and concentration
• help with work and study
• relax and reduce stress
• increase privacy in the home or office
• quiet your mind
• alleviate tinnitus
• calm infants, toddlers, children, and babies
• drown out a snoring partner

### 1/5 — turns on even when app is not open

*2026-08-12, version 6.2.6*

this app used to be good. now not so much. turns on whenever i connect to my car even if the app has not been open in months. super annoying.

### 1/5 — So bad 😫

*2026-08-12, version 6.2.6*

This app literally needs you to pay or else you only have a five minute limit and you can only have restricted sounds so do not buy this app unless you want to pay for the real stuff 😩

### 3/5 — Great app when it works

*2026-06-28, version 6.2.5*

I really like Noise Machine when it’s working properly. The brown noise options are excellent and do a great job helping me fall asleep and stay asleep. The sound quality is great, and the app is simple to use.

My biggest frustration is that it seems to require an internet connection far more often than it should. For an app whose primary function is to play brown noise, white noise, and other sleep sounds, I don’t understand why internet access is necessary. There have been times when I’ve wanted to use it while traveling or during connectivity issues, only to find it doesn’t work reliably.

If the sounds could be stored locally and made available offline, this would easily be a 5-star app. As it stands, it’s a great sleep aid that’s unfortunately too dependent on an internet connection.

### 5/5 — Great noise to sleep.

*2026-06-24, version 6.2.5*

Couldn’t be better

### 1/5 — WTH

*2026-06-13, version 6.2.5*

I’ve paid for this app for a few years and have loved it!! $12.99 for the year, sure! Well worth it. Go to renew my year and find out it’s $8.99 PER MONTH. So disappointed.

### 5/5 — Great!

*2026-06-11, version 6.2.5*

Great!

### 1/5 — App Sucks

*2026-06-06, version 6.2.5*

Worst Fing app.    Do not buy this if you are looking for noise app.  POS

### 4/5 — Default Sound Change

*2026-05-30, version 6.2.5*

I have used this app for years and love it - to the point I now pay for the subscription. The deep brown noise does something to my brain that I can’t describe.

And to that end, it would be amazing if there was a feature (especially when paying) that one could choose the default sound that the app uses. It remembers I want brown noise, but I have to select deep every time.

### 5/5 — Simply the best

*2026-05-19, version 6.2.5*

This app has legitimately been a game changer for me. I can use it with my AirPods while at the laundromat to be able to read (brown noise for this), while in the grocery store so I don’t experience sensory overload (I have a major sensory overload issue)(brown noise for this), I use it every single night if my life for sleep with my HomePod (pink noise is usually my preference for sleep but I occasionally alternate between green and brown as well), I also have ADHD and use this app a lot just from my phone speaker or with my AirPods when I’m just having trouble concentrating in general but especially if I can’t focus while I’m reading. (Brown noise tends to be my go to for this as well).
I also started using this app when babysitting for my best friend and found that pink noise is a miracle worker for babies nap time and sleep time. That friend now uses pink noise in their babies room every single night and has noticed a significant improvement in the amount of time staying asleep and overall quality of sleep for the baby 🖤 

All in all I couldn’t be happier that I paid for this app. I’ve used several different apps and this one seems to create the most consistent, high quality sounds. I highly recommend it to anyone! 

I will say, if you’re using it for sleep, I highly recommend a speaker of some sort because phone speakers just don’t quite do the trick for me personally. Although, you could have a totally different experience; I just wanted to put that out there.

### 1/5 — App Sucks

*2026-05-16, version 6.2.5*

Worst Fing app. While I like noises for sleep this app constantly  locks up and does not load.  Not until I delete it and reinstall does it work. Can’t wait for subscription to run out.  POS
