About Brown Noise for Sleep

What this site is

Brown Noise for Sleep is two things. The first is a free brown noise player. You press play and the sound starts, with no account, no install and no download. The second is a set of plain-English guides about the noise colours: what brown noise is, how it differs from white and pink noise, and what research does and does not show about using it for sleep, focus or tinnitus.

We made the site because many brown noise pages are either a long audio file with ads around it, or an article that never lets you hear the sound it talks about. We wanted one place where you can read about the sound and hear it at the same time. The player does not play a short recording on repeat, so there is no gap or jump to notice in the night.

Who publishes it

ItDeveApps, a small independent app developer, publishes this site. ItDeveApps also publishes the Brown Noise, Sleep Sounds: BRW app on Google Play and Brown Noise for Sleep: Brw on the App Store. The website and both apps come from the same developer and share one support inbox.

You can see everything ItDeveApps has released on its Google Play developer page and its App Store developer page.

To be clear about what we are not: nobody here is a doctor, an audiologist or a sleep scientist. We build sound apps. Where this site talks about health, it reports what published research says and points you to a qualified professional. It never replaces one. See how we check what we write below.

The app

The web player stops after 30 minutes a session. The app plays brown noise with no time limit. Its other sounds are free for one hour a day, and Premium removes that limit. It plays offline, keeps playing in the background, has sleep timers, lets you mix sounds, and has brown, white, pink, blue and green noise. It is free on Google Play and on the App Store.

The Android version has been out since 2025, so it has a public track record. This is what its Google Play listing shows:

• Brown Noise for Sleep: Brw (App Store id 6763829615)

Why there are no ads

An app people fall asleep to is the worst place for a pop-up ad. The app has no ads at all. Optional in-app purchases pay for it. For the same reason, this website has no ad scripts, no trackers and no analytics. The privacy policy explains exactly what that means.

How we check what we write

Many people come here for help with poor sleep, tinnitus or trouble focusing. So a large part of this site touches on health, and we try to hold it to a high standard.

Our rules are simple. Describe what a study actually measured, not what a headline said about it. Say plainly when the evidence is weak, early or mostly personal stories. Give clear safety advice where it exists, such as volume limits for babies. Never suggest that sound is a treatment for a diagnosed condition. Brown noise does not diagnose, treat or cure insomnia, tinnitus, ADHD, or any hearing or sleep problem.

Our app comparison pages take every fact about an app from its own store listing and show the date of the check. When a listing does not mention a feature, the page says so instead of guessing.

If you find something on this site that is wrong, out of date or overstated, tell us and we will fix it. Corrections go to the same inbox as everything else. Getting a health claim wrong is the mistake we most want to avoid.

Your privacy on this site

The site is a set of simple web pages. There is no database, no user accounts and no login, and nothing you do here is stored on a server. A site that stores nothing about you cannot leak anything about you.

The site does not use Google Analytics or any other analytics or advertising script. The only thing saved in your browser is one cookie that counts how long the player has been running, so the 30-minute limit works. The privacy policy explains this in detail, and keeps the website's data practices separate from the apps'.
