amazing app

perfect for making a loud frequency noise and annoying everyone in public it’s so fun great app. no one knows where it’s coming from

Used to work

No longer works and tooo much ads. Not sure if ad runs first and then if you don’t do anything it will not work

DO NOT INSTALL AWFUL ADS YOU CANNOT STOP

First time I had to give a 1 . Awful ad for stupid games that you cannot stop from playing. This app should be reported to Apple and banned. Tried one setting and then ad you can’t turn off.

An app

Good fine works

Didn’t work for me

I put it on fly mode and a fly literally landed on my phone and sat there.

I think the app is a prank

I just think this app is a joke really .

No noise emitted

Non functional on iPhone 11

A Placebo

Great looking application which is a total waste of space on you phone . My cat sleeps on top of the phone while it is on , my dog licks the phone when I put it near him whether or not the app is running . It does nothing .

Does not work

Did not make a difference at all with my cat.

Doesn’t work

The mouse just continued on without a care in the world.
