Synthesised live rather than streamed — no loop, no data usage.
Steady broadband noise masks the sounds that break concentration — a conversation next door, traffic, a neighbour’s television. It is generated in the browser rather than streamed, so there is no repeating loop to notice.
How to use

- 2 Set the volume — lower than feels right is usually correct.
- 3 Set an auto-stop timer if you are using it to fall asleep.

Frequently asked questions
What is the difference between white, pink and brown noise?
White has equal energy at every frequency and sounds hissy. Pink reduces the higher frequencies and sounds like steady rain — most people find it best for focus. Brown cuts them further and sounds like distant thunder, which suits sleep.
Is it safe to sleep with it playing all night?
At a low volume, generally yes. Keep it below about 50 decibels — roughly quiet conversation. Prolonged loud playback close to the ear is not harmless, particularly for children.
Does it use data?
None. The sound is synthesised in your browser rather than streamed, so it works offline and costs nothing on a metered connection.
