The iTorturer app is a free iPhone application developed by Eric Cerney in the Lifestyle category. With this app, you can prank a room full of people by playing a variety of sounds that will drive your friends crazy.

The app offers a range of sounds, including 45000Hz, tri-tone ringtone, white noise, and many others. These sounds can be toggled on and off at the rate of your choosing, creating a torture-like experience for everyone in the room.

One of the standout features of the iTorturer app is the 45kHZ noise, which can be heard even in the loudest of situations due to its high frequency. The location of the noise remains hidden, adding to the prank's effectiveness. You can have a blast tricking your friends into thinking they are going crazy and hearing a ringing that "no one else can hear".

In addition to the pre-loaded sounds, the app also allows you to select new sounds that are added occasionally, giving you the ability to customize iTorturer to the exact situation needed. Whether you want to use a personal recording, a whoopee cushion sound, horror sounds, a fly buzzing, a cricket chirping, a cat meow, or even a police siren, the app has you covered.

Overall, iTorturer is a fun and entertaining app for pranking your friends and creating memorable moments. With its wide range of sounds and customizable options, it offers endless possibilities for driving people crazy.
