Sleep

Sound that fades as you fall asleep.

For the nights when your mind will not put the day down. Choose a length, from twenty minutes to a whole night, and warm music begins, then slows, thins and softens until there is almost nothing left. Every night is composed fresh, and it carries on quietly with the phone locked.

One payment. iPhone, iOS 18 and later. Tuned for a bedside speaker, headphones or the phone.

What it is.

A sound that quietly recedes takes you down with it. That is the whole idea behind Sleep: it gives you a little less to listen to every few minutes, until there is almost nothing there and neither are you.

It asks nothing of you in return. Nothing to set up, nothing to wear on your wrist, and no score waiting for you in the morning. I use it most nights myself. It grew out of the engine I built for my tinnitus, which turned out to be the most relaxing thing on my phone, so I gave it a home of its own.

Two modes.

Wind-down.

Twenty, thirty or forty-five minutes. The music slows and fades to silence as you drift off.

All-night.

Six, seven or eight hours. It descends over the first forty minutes or so to a barely-there floor, holds that quiet presence through the night, and fades out at the end of the hours you chose. Steady enough to soften the noises that wake you, and quiet enough to sleep through.

There is no track list.

Most sleep apps play recordings, the same rain and the same few tracks on a loop. There are no recordings here. The music is composed from scratch while you sleep, every night. Choose Hearth for something warm and glowing, or Rainfall for something almost silent, and change your mind mid-night if you would like to hear the difference.

Once it is running you can forget about it. Lock the phone, put it face down, and the descent carries on regardless, ending in a slow fade rather than a sudden stop. If you do reach for it in the night, the controls are on the lock screen.

What makes it different.

  • Every night is a fresh composition. There are no loops, no samples and no track list. A generative engine writes the music as you sleep, and no night is ever played twice.
  • It gets out of the way. The screen chrome recedes, and the descent carries on whether you look at it or not.
  • Tuned for how you listen. The mix has its own profile for headphones, a smart speaker or the phone speaker, and switches between them automatically when you connect something.

Why a fading soundscape.

Sleep rests on a simple idea: music that slows and softens gives your body permission to do the same. Sound that recedes takes you down with it.

The all-night floor exists for a different reason. A low, steady, unchanging presence softens the household noises that fragment sleep, a partner turning over or a car outside, without ever being interesting enough to wake you.

Pay once, and it is yours.

There is nothing to subscribe to, no account to make and no password to remember. There is no advertising and no analytics, and the app never contacts a server, so there is nothing to send and nothing to intercept. It remembers only your preferences, on your phone.
