White noise is a consistent sound that plays across all audible frequencies simultaneously, creating a steady hiss similar to a fan or static. It masks distracting background sounds — conversations, traffic, notifications — helping you maintain focus or drift into sleep more easily.
Brown noise and pink noise are related but distinct. Brown noise has more energy in the lower frequencies, producing a deeper rumble that many people find even more calming than white noise. Pink noise sits between the two, resembling rainfall or wind through leaves — balanced, natural, and scientifically linked to improved sleep quality.
Why use a noise display?
Sound alone is powerful, but combining it with a calming screen environment multiplies the effect. A plain white or warm-toned full-screen display removes visual clutter and gives your eyes a rest, making it ideal for meditation, napping, photography backdrops, or simply stepping away from content fatigue.

What is a Pomodoro timer?
The Pomodoro Technique is a time management method: work for 25 minutes, take a 5-minute break, repeat. Our built-in timer lets you run Pomodoro sessions while your chosen ambient noise plays continuously in the background.
What are binaural beats?
Binaural beats are an auditory effect created when two slightly different frequencies are played in each ear. The brain perceives a third tone — the difference between them — which can promote relaxation, focus, or sleep depending on the frequency. Best experienced with headphones.
