### 1/5 — Useless/ inutile

*2023-01-18*

Ce produit est une attrape et ne fonctionne pas.

### 5/5 — Trotzdem ❗️❗️❗️

*2016-07-13*

Manchmal funktioniert es. Aber die Höheren Frequenzen können nur Kinder/Junge Menschen hören . VOLL COOL 😎 damit kann man gut Leute veräppeln 😜

### 1/5 — Schade um das Geld.

*2015-08-21*

Funktioniert leider nicht, daher meinerseits Geld vergeudet und andererseits nur Abzocke ...

### 1/5 — Rip off

*2015-07-20*

Doesn't work. Complete waste of money even though only .99 cents!
Gave 1 star because would not allow me to give 0 stars

### 1/5 — Dog ultrasonic repeller

*2015-04-04*

### 1/5 — Schrott

*2013-03-20*

Funktioniert Null , schade um die 0,89 Cent !

### 5/5 — Really good

*2012-07-25*

Great.

### 2/5 — unwirksam

*2012-01-25*

Katzen können auch diese Frequenzen hören sind aber völlig unbeeindruckt und liegen schnurrend vor meinen Füßen. Ich probiere das bei einem Hund lieber nicht aus, sonst hab ich schnell einen iDog. ;-)

### 1/5 — It doesn't work

*2011-09-14*

I have tried this app with multiple dogs and they don't respond at all.  They dont notice it at all and it certainly doesn't repell them.  It's the same thing as the dog whistle app, which also doesn't work.

### 1/5 — Doesn't work at all

*2011-07-16*

I usually don't review apps, but I felt compelled to save others the trouble.

I bought this app to repel packs of feral dogs that roam near the hotel that I typically stay at in Bangalore, India. Most Indian cities have a fair amount of feral dogs running the street. They are harmless during the day, but they can be a problem at night. 

Given the mixed reviews, I decided to try it during the day in low risk situations. I have an iPhone 4, and I used it on max volume. With several dogs over a four day period with various frequencies, I experimented with the app. The greatest effect that I was able to achieve was that on one day some dogs looked at me and pointed their ears in my direction. It didn't repel them at all. In fact, I walked within 6 inches of a sleeping dog with it on, and the dog didn't even stir!

Don't waste your money.
