Dog Whistle - 3D Sound with adjustable frequency, is the perfect app to train your favorite pet. By using a special "3D Audio Technology" and an adjustable pitch, this app can fit the need of most animals, because not all react to the same frequency sounds.

Find the best whistle sound that your pet reacts to and you'll be set for a perfect training.

No need to select between presets that don't work like in other apps. And the bonus is that if your pet gets used to one high pitched sound, you can always vary it just a little bit to get his attention again and be sure that the training is not interrupted.

The 3D sound technology works by creating a second wave like sound at an even higher pitched frequency which is inaudible to humans. When the sounds are combined, they complement each other to create a perfect tool to train and get your dog's attention.

Try it, you will not be dissapointed!
