Stealth Tone
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 ("Activiate" button). It also includes an audible sound similar to a grenade dropping ("Dropping tone" button).
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.
If you're an adult hosting a party and want to drive teens away, hook up this app to some speakers and watch the underage kids leave!
Got a younger sibling you just can't stand? Crank it up!
Disclaimer: 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. Please read the standard App Store EULA for more detailed information.

This app hurts my ears really bad. And yes I can here the stealth tone. I'm 8 years old.
Well under 20 but I can't hear. Neither can anybody else. Only certain people can hear it. Practically useless. 3 stars because at least the dropping tone works.
I tested it cause it says people over 20 can't hear it and I tried it on my 47 year old dad and he didn't hear a thing
Fun app, but add an option to have timer do dropping tone would be nice.
I had this app on my old LG Optimus and it was awesome. Now I have a newer LG and the tone is audible to me and it doesn't have the effect on people or animals that it used to, I used to implement the tone as a dog whistle for training and now my dogs don't even flinch at this new version. What happened?
I thought I can hear the Noose from Speakers but no… Could you try to add some more sounds !!
I rate it 5☆ but it could be alote louder for activate its a great app I will use it on people that annoy me and see how good it actually is
Been using this app since High School. It never get gets old lmao! Probably the best app for annoying people haha xD
I wanted to use this in church because there was this annoying little kid and it shut him up nicely
It sounds like a faint natural gas leak, but the dropping tone is easier to hear. It works as advertised.
I tested it on my 10 year old nephew and it drives him nuts. I can't hear a thing.
I at perfect for annoying your teacher. My friends and I put in on at the same time and she was searching the whole room and looked like an idiot while doing it. GET IT!!!
Mom can hear drooping tone,but it is understandable
Been Using it for 6 years now
Not sure if this is good or bad, but I'm 32 and can hear the alarm tone perfectly...
Nice app to troll all of my friends... they were like "what was that???" Anf i iust go " i don't know.. how the hell should I know"..... hahahahahahah
One cool app to have fun with. Thanks.
Don't waste the space on your phone
Very funny great reations
Good to pull pranks with😀😀
That is really loud!
the apps download says error code 919 and 921...what is this?
Bad to the bone
Really cool
Love this app
This really works...
I'm over 20, but under 30. I can only hear the sound w my ear on the speaker... even then, its just a hum. I also get a headache when its on (ear not up to speaker), which would be scary if I didn't know it was me making the sound. Point is: it definitely does something, but I won't try it in public bc I can see bad things happening. Plus, I fear it may ruin my phone speakers. Interesting though!!!
Having tried similar apps without much success I was sceptical. But when a young woman sat in the seat behind me on the commuter train during rush hour and started yapping away on her phone like no one else was around her I decided to try it out. I couldn't hear a thing, but after letting it run for about a minute, she got up and moved to another car. Success!
