Why it's free

The app is free because the channel pays for it.

Our long-form ambience videos earn ad revenue on YouTube. That funds the app, which means we never have to charge you for the sounds — and never have to put ads inside a thing you fall asleep to. There is no paywall on any soundscape, and there never will be.

Free forever · No ads in the app · No account

Scenes

Six worlds, each with its own mix.

Every scene pairs a looping film with two or three sound layers you can balance yourself — pull the rain back, push the room tone up, find the version that works for you.

• 
  Rainforest

  Rain in the deep canopy
• 
  Rainy Window

  Storm on the glass, warm inside
• 
  Fireplace

  Crackling cabin fire
• 
  Ocean Waves

  Dusk swell on an empty shore
• 
  Thunderstorm

  Rolling thunder over dark plains
• 
  Space Station

  Earth below, engines humming

In the app

Built for the moment you stop looking at your phone.

• A mixer, not a playlist

  Balance each layer of a scene by hand. Three pure noise options — white, pink, brown — sit on their own.

• Sleep timer that fades

  Set it and the sound falls to silence over thirty seconds, so nothing snaps off and wakes you.

• Works offline

  Every sound ships inside the app. No streaming, no buffering, and it keeps playing when the screen locks.

• Nothing to sign up for

  No account, no email, no profile. We do not want your data and have nowhere to put it.

The channel

Eight hours at a time, on YouTube.

The same soundscapes and the same films, uploaded long enough to sleep through. Watching is what keeps the app free — and it is the only thing we will ever ask you to do.
