This is a simple app to play with. It has a very simple interface and simple controls. It also provides you with the option to use either a sine wave or a square wave. It can also provide you with the option to choose between a frequency range of 10 KHz to 20 KHz or a frequency range of 200 Hz to 1 KHz.

The main purpose of this app is to search for the resonance frequencies of a body. This is done by using the different options that are available.

The way this is done is by first setting the frequency. Next, you need to set the time and the type of wave. Now, you need to click on the Start button to start the process.
