No. 19 The Ardenholt RegisterIn the press for 2026Mind & Body Est. MMXXVI

Nothing to stream, so nothing to renew.

Sleep sounds generated on the device — no downloads, no loops, no library to subscribe to.

Every sound in Hush is synthesized in real time rather than streamed from a catalogue, so nothing repeats, nothing buffers, and it works in airplane mode forever. That architecture is also why it can be sold once: there is no server to pay for.

§ I

§ I — The program

The sound is made,
not played back.

What Hush generates, why generating it removes the server, what removing the server does to the price, and the line a sound app has no business crossing.

A recording always comes back around

Almost every sleep app plays a recording: a few minutes of rain, joined end to end and left running. The join is the problem. Somewhere in the small hours your ear stops hearing rain and starts hearing the seam — the same drip in the same place, the same swell arriving on the same beat — and once it has been noticed it cannot be un-noticed.

Hush has no recording to join, because nothing was recorded. The rain is computed as it falls, sample by sample, for as long as the sound is on. Eight hours of it contains no repeated minute, not because the library is large but because there is no library.

No seam to find

No file means nothing to fetch

A streamed sleep sound has a dependency nobody mentions at bedtime: the network. A cabin with no bars, a plane at altitude, a router that gave up at midnight, a data cap reached at eleven — each of them is a silent bedroom in an app that needs the internet to make noise.

Because the sound is arithmetic rather than a download, there is nothing to fetch and nothing to cache. Airplane mode changes nothing at all. That is also the whole of the privacy story: an app that never opens a connection cannot report what time you fell asleep, and does not have to be trusted not to.

Airplane mode, forever

No server, therefore one payment

This is the part the price rests on, so it is worth saying plainly. A subscription to a sound library is not arbitrary greed — a catalogue has to be hosted, transcoded, and served every night to everyone, and somebody has to pay that bill every month it exists. The recurring charge is the recurring cost, passed on.

Hush has no catalogue and no delivery. Once the app is on your phone, using it costs us nothing at all, forever — so charging you every year for it would be a decision, not a necessity. One payment of $19.99 — no sound packs to buy. Not an introductory price, not a tier below a better one, and not a purchase that turns into a bill the year after.

The architecture is the price

A sound app, and it says so

What steady sound reliably does is mask: it raises the floor of a room so the door, the siren and the neighbour's shower arrive as small changes instead of alarms. That mechanism is ordinary acoustics and it works. What it is not is a treatment.

So Hush claims no proven frequency, no measured increase in deep sleep, and no cure for anything. Insomnia that has lasted a month, snoring with gasping in it, or daytime sleepiness that costs you the day belong with a clinician — the first-line treatment for chronic insomnia is CBT-I, not an app that plays rain. We would rather sell fewer copies than imply otherwise.

Masking, not medicine

The oath attached to the price

Seven days free first, with every sound and every mix running and no card asked. After that, one payment of $19.99 — no sound packs to buy: the whole library, the mixer, the fading timer, and whatever is added later. There is nothing to renew and nothing to cancel.

Thirty days, money back, no reasons asked. Fully synthesized: no audio files, no streaming, offline — so your mixes and your settings sit on your phone, and nothing about your nights exists anywhere we could lose it, sell it, or be asked to hand it over.

No ads interrupting a sleep app, which should be obvious. Not a banner, not a house promotion, not a sponsored soundscape at two in the morning. An advertisement inside a product whose entire job is to let you stop paying attention is a contradiction, and no price makes it one we would take.

The house's word

The measure of a sleep-sound app is not the evening it sounds beautiful in a shop demonstration. It is the fourth hour of the fourth night, when the rain is still rain and your ear has never once found the place where it starts again. Nightshift, No. 05 in the same register, works the other side of the same night — the schedule rather than the sound.

Standing prohibitions

Five things Hush will not do, held as terms of the program rather than as a roadmap that can quietly change.

No subscription, no sound packs, no premium library behind the one you bought
No ads, no sponsored soundscapes, and no house promotion at two in the morning
No account, sign-in wall, or email address asked for before a sound will play
No network call from the app — nothing to send, so nothing about your nights is collected
No invented science: no proven sleep frequency, no claim to treat insomnia or tinnitus

§ II

§ II — The purchase

Bought once, because
it costs us nothing after.

The price is not a promotion and not an introductory rate. It is what a program with no server to run is worth charging for.

One payment

$19.99

Seven days free to run the whole thing, then one payment and it is yours — every sound, the mixer, the fading timer, and the sounds added after. Nothing renews, nothing lapses, and nothing has to be cancelled the year you forget about it.

§ III

§ III — Questions

Asked at one in the
morning, answered here.

The questions people actually arrive with: whether the seam is real, which noise to pick, why this one is not a subscription, and what a sound app may honestly promise.

"It never loops" — is that a real difference or a slogan?

It is a real difference and it is testable. A looping app plays a recording of a few minutes and restarts it; the restart is a physical event in the audio, and after enough nights your ear learns where it is. Hush computes the sound as it plays, so there is no recording and no restart to learn. The practical test is the fourth hour rather than the first minute: put any sleep app on for a full night and listen for the place where it starts again. In Hush there is no such place, because the rain that fell an hour ago was never stored.

Which should I sleep to — white, pink, or brown noise?

There is no crowned winner in the research, and anyone selling you a "proven deep-sleep frequency" is selling something. The three describe how sound energy spreads across frequencies, and the practical difference is texture: white is a bright, full-spectrum hiss, pink softens the top end into something rain-like, brown drops lower still into a rumble. Most people find white harsh at the volume masking actually needs and find brown the easiest to live under for eight hours. Try each for a full night, not five minutes, and pick the one your ear stops following.

Why is this one payment when the big sleep apps are subscriptions?

Because their bill is real and ours is not. A sound catalogue has to be stored and streamed to everybody, every night, which costs money every month it runs, and a subscription is an honest way to pay for that. Hush ships no audio at all — the sound is generated on your phone — so once the app is installed there is no ongoing cost on our side to recover. Charging annually for that would be a choice we made, not an expense we had, which is why the price is one payment of $19.99 and there are no sound packs behind it.

Does it work in airplane mode, and do I need an account?

Yes, and no. There is no audio to download and no stream to open, so a plane, a cabin with no bars, a dead router or a spent data cap all leave the sound exactly as it was. There is no account either — no sign-up, no email, no login standing between you and the dark. That is not a privacy policy so much as a property of the code: an app that never opens a connection has nothing to send.

Can it help me sleep with tinnitus?

Many people use steady sound to make ringing less noticeable at night, and a full, even wall of sound with no gaps or seams is the shape that tends to work best — which is what Hush is. Choose a texture that sits near the pitch you hear and let it run past the point you fall asleep. But that is masking, not treatment: it does not cure tinnitus and does not slow it. If yours is new, changing, or wearing you down, that belongs with a doctor or an audiologist rather than with an app.

Will it actually make me sleep better?

It will give you a steady, never-repeating sound to settle into, and if noise is part of what wakes you, masking it is straightforward acoustics rather than a promise. Beyond that we will not claim much: studies of noise as a direct sleep enhancer are small and mixed, and we are not going to quote them as though they were not. Try the same sound at a modest volume for two weeks and judge by your mornings. If it does nothing for you, that is a real answer too — and the thirty-day guarantee is there precisely so finding it out costs you nothing.
