About this app

This app generates a constant tone (sine, square, triangle or sawtooth wave) in the audible frequency range (20Hz to 22KHz) which may be adjusted in 1Hz or 10Hz increments. In addition, special sounds can be played to remove the water from your speakers and to help you relax, meditate and sleep better. Each of these main sections of our app is on a separate page, and more information about them will be displayed when you tap the About button. What else this tone generator can be used for?
