Two questions

Which sound should you start with?

Most sound apps hand everybody the same list and let you dig. This asks what you are actually doing and what you cannot stand, then names one thing to try.

What the app does with this

The version above is two taps and a fixed answer. In Luten you say how you feel in your own words, and Sona reads it on the phone itself using Apple's on-device language tools. Nothing you type is sent anywhere. It also learns which sounds you keep and which you skip, so the answer stops being generic.

Luten is free to download on the App Store for iPhone. The subscription is optional and every subscription starts with a 7 day free trial.

Every answer, in one place

Fifteen combinations, so you can read them without answering anything.

Get back to sleep · A voice ruins it

Three In The Morning

Very low cello and double bass, one dark chord held with almost no movement in it.

Nothing in the Luten catalog has a voice in it. No narration, no singing, no one telling you to relax. This one was written for the exact hour you are awake in.

In the Sleep section of Luten.

Deep Pink Noise

Pink noise with the highs taken away. Deep and close.

No melody to follow, because there is no melody. Pink noise sits between the hiss of white and the rumble of brown, and this version has the top rolled off so it stays soft across a long night.

The Long Middle

A single sustained cello note, almost motionless from the first second to the last.

It does not build and it does not resolve. There is nothing coming that you need to stay awake for.

Parallel Play

Sparse felt piano over distant room tone. Company without conversation.

Some people find it easier to begin when the room does not feel empty. This is that room, and nobody in it is going to talk to you.

Steady Brown Noise

Brown noise held completely level. One thing to hold on to.

Brown noise is a preference, not a treatment, and we will not tell you otherwise. What is true is that this one is synthesised to its actual spectral slope rather than made by pulling the treble off a recording, and it does not move.

One Thing At A Time

One sustained reed organ tone with the slightest movement in it.

The whole track is the first second. Nothing arrives later.

Pure White Noise

Flat, even white noise. The same from the first second to the last.

The worst office sound is a conversation you can almost make out, because your brain keeps trying to finish the sentence. Covering speech is a question of acoustics rather than wellness, and broadband noise is the plainest tool for it.

Page Turns

Pages turning in a still room, sparse and quiet, like a library desk nearby.

No tempo anywhere in it. Lo-fi has a beat, and a beat is a thing to follow. Half an hour in you are nodding along instead of reading.

Steady Pink Noise

Pink noise held perfectly level, with nothing to notice.

Deliberately uneventful. There is nothing in here worth turning your head for.

Low Cedar Stillness

Solo cello, long slow bows in the low register, woody and grounding.

One instrument, no words, no guide. If wordless choirs still read as voices to you, this has none of that either.

The Long Exhale

A descending pad whose fall is always longer than its rise.

Shaped rather than composed. It is a slow shape repeating, not a piece of music going somewhere.

Empty And Still

A near-silent sine pad, mostly space.

Closer to a quiet room than to a track. Most of it is the space between.

Kiri no Komoriuta

A Japanese lullaby on solo koto, sparse and full of space, with a breathy shakuhachi far away.

The lullabies in Luten come from all over the world and every one of them is instrumental, so nothing is being sung at a child in a language they are meant to understand.

Soft White Noise

White noise with the top softened. Gentler over a long night.

For a child who settles to a hush rather than a song. No tune, nothing that ends.

Bíum Bíum

An Icelandic lullaby on harmonium, sustained and very still, the reeds just audible.

It circles rather than develops. Nothing in it wakes anybody up.

Questions people ask before they download

Is there any talking?

No. There are no vocals anywhere in the catalog. No narration, no guided meditation, no course.

Does it play with the screen off?

Yes. Audio keeps going in the background and on the lock screen, sounds download for offline playback, and the player stays black while it plays.

Are these claims about what sound does to me?

No, and deliberately not. The descriptions above say what a sound is, not what it will do to you. Whether something suits you is your call, not ours, and how long you listen is your business.

Is it free?

It is free to download. The subscription is optional and every subscription starts with a 7 day free trial.

More on the specifics: sounds for waking at 3am, sleep sounds with no talking, white, pink and brown noise, rain sounds with no thunder, fan sounds for sleeping.
