Sound Terrain

Noise that has never been recorded.

Every other white noise app loops a file. Around twenty minutes in, your brain finds the seam.

Sound Terrain running on iPhone: a dark surface with a single ember puck, saved sounds along the top, and a timer ring below showing 15, 30, 1H, 2H and NIGHT.

Your brain is very good at finding the loop.

It works for a while. Then the seam arrives, and once you have heard it you listen for it. The thing that was supposed to hide the world becomes the thing you are paying attention to.

Sound Terrain has no file to loop. The sound is synthesised sample by sample, all night, and no two seconds of it are ever the same.

No sliders. No mixer. No twelve band equaliser.

Find a sound by moving one puck, name it, and from that night on playing it is one tap.

The opening screen, explaining the surface in a single sentence.
The whole idea, said once, before you touch anything.
The sleep timer, drawn as a ring that closes rather than a countdown.
A timer drawn as a closing ring. A number is a thing a sleepless person lies there watching.

Built for the dark

True black

An OLED screen emits nothing it does not have to. Controls recede rather than announce themselves.

It leaves slowly

The sound fades out over three minutes. Silence that simply arrives will wake you.

Nothing is collected

No account, no advertising, no analytics. The app makes no network requests at all, because there is no server to send anything to.

Where you expect it

Works with the lock screen, Control Centre, AirPods and VoiceOver.

Free to fall asleep to. One purchase to sleep to.

The surface, every colour, the swell and unlimited saved sounds are free, with no time limit. The only thing that costs anything is the whole night.
