Press play for deep, steady brown noise.
Brown Noise Player generates smooth, deep brown noise in real time. There are no audio files inside it, so nothing ever loops, nothing repeats, and the sound keeps going for as long as you need it.
For studying, deep work, a noisy office, a restless night, or a baby who only sleeps to a fan.
SIX BROWN NOISES, FREE
Classic - balanced, steady brown noise
Smooth - soft and round, more low rumble, no hiss
Deep - darker and heavier, like distant thunder
Warm - softer top end, gentle and close
Ocean - slow rolling swells, like surf
Rainfall - brighter and airier, a steady downpour
All level-matched, so switching never jumps in loudness.

No review analysis published for this app.
“Not assessed” means we could not measure it. It is never a zero and never a pass.
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.
Supporting measurements: not a complete list of possible harms or positives. Measurement vocabulary 1.4 · how these are measured

Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.
New: Smooth, a sixth free sound. Soft and round, with more low rumble and no hiss. If you know the brown noise everyone plays on YouTube, this is that sound, generated live so it never loops. It's second on the main screen.
Appworthy
brown-noise-playerWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
These are really on sale; we just can’t tell from the name whether they recur.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
