Ambient noise for sleep and concentration

Sound that never repeats itself

White, pink and brown noise. Rain, ocean, a box fan, a fireplace. Thirty-three layers you can stack into one sound to fall asleep to, or to disappear behind while you work.

Every layer is synthesized on your device as you listen, so nothing ever loops — and nothing is streamed or collected.

Why it sounds different

Every competitor is playing you a recording

A rain track is a few seconds of audio repeating for eight hours. Once you have heard the seam, you cannot unhear it — and at 3am you have nothing to do but listen for it.

Duskloom has no audio files at all. Rain is noise through filters with individual drops landing at random. Ocean waves swell every eight to fifteen seconds and never twice the same. A fireplace is a bed of embers with crackles scheduled as they happen.

Because it generates rather than streams, it works in airplane mode, in a basement, on a flight. It makes no network requests at all — nothing to collect, no account to make.

A looping recording

Watch the seam come round again

Duskloom

Generated as it plays — no seam to find

Nothing loops

Two nights of the same mix are never the same audio. There is no seam because there is no recording.

Fades, never cuts

The sleep timer ramps to silence across the final minute. The ending is what wakes you.

Plays with the screen locked

All night, with a wake alarm that fades the mix down before a bowl rings, gently.

Colour follows the sound

Every layer has its own hue. The whole screen takes the blend of whatever you play.

The library

Thirty-three layers.
Mix as many as you like.

Each has its own level, so a fan under brown noise under rain is one sound rather than three. Save the ones that work.

Questions

Reasonable things to ask

Does it really not loop?

Really. There are no audio files in the app to loop. Noise is generated sample by sample, and events like raindrops, thunder and crackles are scheduled at random times as they occur. Leave the same mix running for eight hours and no two minutes are identical.

Will it keep playing when my phone locks?

Yes. It declares itself an audio app to iOS and runs a playback service on Android, so it plays all night with the screen off and appears on your lock screen.

Do you collect anything?

No, and not as a policy choice — the app makes no network requests, so there is no channel through which anything could leave your phone. Put it in airplane mode and it behaves identically. Levels and saved mixes stay on the device.

What is free, exactly?

All seven noise colours plus rain, ocean, wind, fireplace, box fan, stream and crickets. Unlimited playback, background audio, the sleep timer and the breathing guide are never locked. Tap any paid sound and it plays for thirty seconds, so you hear what you would be buying before you pay.

Is there a subscription?

No, and there will not be one. A subscription pays for recording, licensing and hosting. We have none of those costs.

Does it help with tinnitus?

Many people use coloured noise for it, and Duskloom generates white, pink, brown, green, blue, grey and violet noise properly rather than playing a recording of them. We make no medical claim — speak to an audiologist about what is right for you.
