High Pitch Blaster

This is one of the craziest apps I've ever seen. I set it on the highest frequency and pressed the button. Within seconds three of my kids were like "WHAT IS THAT SOUND!" I didn't hear a thing. Crazy. But just as a caution, it's really uncomfortable for kids as it hurts their ears.

My cousin was being annoying yesterday so basically I play this and instant payback. He can hear it from across the house!

Welp, I found something for senior prank day when I'm a senior in 2 years. It seems older people can't hear it so I'm pranking the students.

I found out this app existed during a test. Yes i failed that test. And yes ouch my ears. Still love it

Stupid kid was hitting the back of my seat, and being generally annoying. He hated this and couldn't tell where it was coming from

No one could hear any sound, even with volume turned all the way up. My 6 yr old even said she couldn't hear it. Uninstalling immediately.

The problem is I download this app to deter dogs when I'm on the street doing my walks. It stops whenever my phone screen sleeps. I have to constantly touch my screen to keep it on...

Well I will definitely be able to tell you after 16/08/17 when I walk past a particular address or maybe more. It will be ready for any dog! Just a deterrent against barking dogs.

I installed because the neighbor's dogs were barking alot at night and after turning it on for roughly 5 secs, there was no more barking.

Its funny when you cant hear annything but the people around you are freaking out, set it off in the cafeteria at school, it went silent for a second while the teachers didnt hear a thing.

No good if you want to set it and leave, pop up ads keep stopping the app.

Love it.. Use it to stop dogs from barking and sure gets the kids away from the "adult" table in a hurry

It's amazing I did this prank on my baby brother and he freak out about it!!! Just need a higher pitch and needs to be little bit louder

This app works with no issues. Great for pranks and hearing tests. It hurts my ears a lot, though.

For a high pitched sounds it didn't even faze my dogs

Lmao kids hate it. Dog hates it. I cant hear it. :D

It messed my phone's speakers n it doesn't work

Funny to annoy friends

I love it I used it to any my sis she said it hurt her ears but it didn't really hurt mine tho

This app is good for annoying the crund out of your friends

Wgats the point? Maybe you can prank your friend? Theres just no point for this app.

I like it but could you make it so that it has an option run in the background please?

I love love love this app coz my cuzzie had it and I was super jealous so I downloaded it myself lmk

I use this on my roommates when they are being to loud

Not loud enough, I intend to use this for self defense

Omg this is the best thing ever on the highest frequency I can't here it but it makes my brother cringe XD

It makes my dog freak out

It actually plays a really high frequency. Great with cats lol

Works great with dogs, my friend's cat, tank, ran away with my prosthetic arm.

I love how I can make other people suffer with this app

I was cranked and I had to download it

I hurt people s ears

I am a kid and I instantly got ear raped

I pranked my mum she hated it!!! My ears are still ringing!!!

IT'S AWESOME lol its very good for annoying the crap out of anyone

Pranked my brother when he was playing the ps4 for about four times xD

There are much better free frequency apps on the market. This one is simply inferior.

It is awesome hide it and put it on and it is perfect prank tool

Funny to annoy friends

Not loud enough, I intend to use this for self defense
