Frequently asked questions
What is the difference between white, pink and brown noise?
White noise is bright and even across all frequencies; pink noise is softer and more balanced; brown noise is a deep, low rumble. Many people find pink or brown more relaxing for sleep.
Does it stream or use data?
No. The sound is generated on your device, so nothing streams — an all-night session uses zero bandwidth and works with no internet at all.
Is there a sleep timer?
Yes. Pick a duration and the sound fades out gently and stops on its own.
Does it work offline?
Yes. As a PWA it keeps generating sound with no connection once loaded.
