Sleep sounds for adults

Quiet nights, on purpose.

Natural soundscapes and a calm wind-down routine, designed to get out of your way. No account, no ads, no tracking, and nothing that wakes you at 3 a.m.

What we're doing differently

It gets quieter as the night goes on

Set a loudness curve once. It starts where you like, eases down over the first hour and settles low, so you're never lying next to a loud room all night.

Built with your hearing in mind

Overnight is a long time to listen. A built-in volume ceiling and a plain-words note on safe listening mean the loudest setting is never the default.

Honest about sleep

Sound can make a room feel calmer, and that's all we'll say. No promises of cures, and if sleep trouble goes on for weeks we'll point you to a doctor.

Nothing to manage

No account, no streaks, no sleep score to feel bad about. Open it, press play, put the phone down.

What we're building

Natural soundscapes

Rain, sea, forest and wind that loop without a noticeable seam, plus steady noise colours such as white, pink and brown.

How it will feel

  1. Set it once

    Pick a mix, a length and how quiet it should end up. The loudness curve eases down over the first hour and settles low for the rest of the night.

  2. Wind down

    Give the last half hour to the routine — dim the screen, a few slow breaths, then sound. Skip it any night; the soundscape works on its own.

  3. Let it fade

    Through the night the volume follows your curve and ends near-silent. Nothing restarts and nothing pings you awake.

  4. Wake to nothing

    No sleep score, no streak, no good-morning notification. The app did its job and stayed out of the way.

What it will never do

  • No ads, and no account or sign-up
  • No tracking or analytics in the app
  • No microphone: it plays sound, it doesn't listen
  • No sleep score or streak to chase
  • No cure claims: it's a relaxation tool

Questions

How quiet does it actually get?

You choose the end volume. The curve eases down over roughly the first hour and settles at the level you picked — usually quiet enough to talk over, and it can end near-silent.

Will it record me while I sleep?

No. It's designed to play sound, not to listen, so it won't use the microphone.

Does it replace treatment for insomnia?

No. It's a relaxation tool, not a medical device or a treatment. If you've had trouble sleeping for weeks, talk to a doctor.

How is it different from White Noise Sleep?

White Noise Sleep is for settling babies and has tools for parents. This app is for your own sleep: a wind-down routine, an overnight volume curve and a calmer, adult look.
