Quieto: Sleep & White Noise

Estanislao R. Pérez Nartallo

About this app

Fall asleep to sound that's never the same twice. Quieto is a sleep sounds and white noise app that generates every sound live on your phone — it's not a looped recording, so there's no repeating seam to notice at 3 a.m.

10 AMBIENT SOUNDS, GENERATED IN REAL TIME
• White noise, pink noise and brown noise
• Rain sounds and a storm, with distant thunder
• Ocean waves rolling onto the shore
• A stream running over stones
• Wind moving through the leaves
• A crackling campfire
• A low ambient drone

A SLEEP TIMER THAT FADES OUT WITH YOU
Set a sleep timer and the sound — and the on-screen scene — fade out together on a gentle curve tuned for falling asleep, not a hard cut. Playback keeps running in the background and from the lock screen while you sleep.

100% PRIVATE, NO INTERNET NEEDED
No account, no ads, no analytics, and no internet connection at any point — Quieto never uploads anything, because it never connects to anything.

FREE, NO CATCH
All 10 sounds, unlimited, from the first launch. No in-app purchases, no subscriptions.

A calm dark interface with a soft animated scene behind each sound — turn animations off any time to save battery. Available in English and Spanish.

What’s new

Quieto 1.1.0 updates the libraries the app is built on, for better stability and compatibility. After you have listened for a while, Quieto may now occasionally ask if you would like to rate it. Thank you for listening, and sleep well.
