UltraSound Whistle (FREE) App Reviews

Good app but if you hold your finger on it for more than 10 seconds it sticks and it keeps ringing even after you take your finger off the screen

AWSOME

None of these things work guess I have to go buy a real one

My dog doesnt react to this

It works but if u think u cant hear one of the frequencies dont put it by your ear 5 star from me

This app does not work only 2mins later he jumps 4ft in the air the goes crazy!

The frequencies it says are wrong, we cant hear 40 kilohertz as humans but i can easily hear what it says is 40 kilohertz.

This app does nothing except advertise for a purchase. SCAM

This app should not be an app it is stupid and people keep hurting outer peoples ears

This app doesnt work at all. The only ears it controlled was mine! My dog wasnt even affected. He woke up cause WE heard it and then went back to sleep. Sorry Im not hurting my ears anymore.

FAKE!!

It totally works, and isnt confusing like most apps!!!!

Useless. My cat is completely deaf to it.

Research shows a "dog" whistle should be equally or more effective on cats. My cats acted as if they did not hear anything at any frequency. I tried on neighbor dogs as well, no effect. App spams ads which is a strong detractor, even if it works. It even took over my screen and tried to get me to a bingo app. Seems like pure spam.

INCAPABLE of producing these frequencies. You can hear the 12000 - 18000, but the phone is actually making no sound at all above 20000. I find it hilarious that this is even in the app store seeing as how the speakers on these devices cannot even produce sounds at the listed frequencies. Lol. Just lol.

I can hear the tone at 16000 Hz. My dog has no response to anything above that and obviously I cant hear it to tell if it works either. Also prepare to be bombarded with ads and you will have to hold the button the whole time to make a sound; tapping to turn "on" is only in the paid version

Its just an ad.

Fake App that links to a copy of Bejeweled.
