TeenHater is the free version of the most intuitive, useful and simple to use ultrasound generator on the App Store.

It can generate ultrasounds from 8 to 22 kHz (limited to 13 kHz in free version) and supports background mode too.

You can use it for testing your own hearing or for drawing attention to yourself without older people noticing you.
