Annoy-A-Tron Lite app for iPhone and iPad

It is said that the range of human hearing is 20-20,000 Hz. Most people 24 and under are able to hear the full range while most people 30 or older cant hear past 16 kHz. Annoy-A-Tron brings the most annoying of these tones to your iPhone/iPod Touch. There are three annoy modes to choose from and all are sure to drive anyone crazy:

Lite version features:

Two tones
-4 kHz to verify the sound is working on your device
-15 kHz that most people can hear

Sound Mode:
This mode plays the frequency youve selected continuously until you touch the Stop button.

Annoy Mode:
Plays a 2 second burst randomly every 30 seconds

Full version features:
-4 kHz to verify the sound is working on your device
-Frequencies that start at 10 kHz and go all the way to 20 kHz
-Continuous sound mode
-Annoy mode
-Timer mode


The iPhone/iPod Touch speaker is limited and gets quieter at the higher frequency. For better results at these frequencies hook your device to a home stereo or car stereo and turn up the volume. Be careful though, setting the volume too high could cause damage to your speakers or even worse, your hearing. Use at your own risk.

First gen iPod Touch users will have to have a speaker hooked up to their device to hear the sounds.
