White Noise Timer
Choose a noise and how long it plays, then press start.
Start with the volume low. Keep this tab open; phones may stop sound when locked.
White, pink or brown
White noise has equal energy across frequencies and sounds like a hiss. Pink noise is softer at the top, closer to steady rain. Brown noise is deeper again, like a distant rumble. When the timer ends, the noise fades out over a few seconds rather than cutting off.
For a short rest, pair it with the power nap timer. For focus, the timer with music or meditation timer.
Frequently asked questions
Is it safe for babies?
Keep any noise quiet and well away from a baby's cot. Health groups advise low volumes; ask your doctor or nurse if unsure.
Will it work if my screen locks or I close the tab?
Only while the page is open. The countdown keeps time from your device clock in a background tab, but phones and laptops can pause or silence web pages when they sleep, lock or close the tab. For anything that really matters, also set your device's own alarm.
