SwingleSonic SLEEP
Read full descriptionHide full description
The SLEEP TM apps gently calm brainwaves that can prevent sleep while simultaneously influencing the enhancement of brainwaves that bring one to sleep. Above and beyond the subthreshold harmonics influencing the core mechanisms of the brain, the perceptible overlay sound is most soothing, resembling a rhythmic breeze rustling though leaves or the gentle ebb and crest of calm waves at sunset.
