Stealth Tone is a special tool that most 20+ year olds cannot hear! Due to a special frequency, you can play this annoying sound in stealth mode.
Great for various scenarios! If you're in a classroom and want to play a practical joke on your classmates without the teacher ever knowing, this is the perfect utility.
Do not play the sound provided by this application at a high amplification or for a prolonged period of time as it may damage your hearing.
It also includes an audible sound similar to a grenade dropping.
