The 'beep' app uses extremely high frequency sounds to alert users of incoming calls or texts. The interesting thing about Beep is that its aim is to let kids communicate with each other -- without their parents noticing.

As people age, the upper range of their hearing decreases. With this in mind, Beep sends notices at 14,800 hz, a frequency most adults can no longer hear. This youth-centered app may strike adults as encouraging the wrong thing, but kids will definitely love it.

The app's creator wanted to give youth and teens a means of communication and collaboration in areas that they typically have no freedom. With the Beep app, it has never been easier to getting away with using your phone in classrooms, libraries and even the dinning table.
