How it works
Binaural Beats
Different frequencies in each ear create a rhythmic pulse your brain perceives, helping with focus.
Noise Layers
Layer brown, green, pink, or white noise on top of any mode using the buttons below.
8D Spatial Audio
Immersive panning creates a moving soundscape that keeps ADHD brains engaged.
Free deep sleep sounds with delta beats and brown noise
Slow delta-range binaural beats blended with soft brown noise. These sleep sounds are generated live, without a recording that loops. If you prefer rain sounds for sleeping, try the thunderstorm mix instead.
How to use it
Start it in bed at a low volume. Sleep headphones or a speaker both work, but you need headphones for the binaural layer.
Who it helps
People with racing thoughts at night, light sleepers, and anyone who sleeps better with background sound.
Common questions
What sounds help you sleep?
Steady, low sounds like brown noise, rain, and soft drones tend to work best, because they mask sudden noises without being interesting enough to keep you awake.
What color noise is best for sleep?
There is no proven best color for everyone. Brown noise is deep, pink noise is softer than white, and white noise is brighter. Start with whichever feels comfortable and keep the volume gentle.
Are delta waves good for sleep?
Delta waves happen naturally in deep sleep. Delta binaural beats are popular for sleep, but the research on them is still early.
Will it keep playing when my phone is locked?
Yes, on most phones. If your phone pauses it, a card will appear so you can resume with one tap.
