Mosquito Sound description

Did you know adults can't hear high frequency sounds that teenagers can? Well with this app you try yourself.

This app emits a high frequency sound (at 17.4kHz) that usually only young people can hear (<21) so with this you can annoy your teenage friends.

The app has a basic one button user interface, and should be easy for anyone to use.

*Also should note, this app has multitasking, so even if close the app, the sound will continue to play until you stop it.
