Dog Whistle Trainer

"Dog Whistle Trainer" is a perfect application for dog training. It can generate high frequency (ultrasonic) sounds that can be heard by dogs, but are inaudible for humans.This way you can train your dog anywhere without disturbing other people. Moreover your dog will learn faster, because it is way much easier for your pet to distinguish pure tone than verbal commands.Just use ultrasonic sound instead of giving your dog a command. For example:Play 2 sec. of 18 kHz sound instead of saying "Sit". Try to learn dog, that it has to sit after the sound has been played. Repeat it for a couple of days and your dog will react and sit down as you wanted to.This app can be also used to scare unwanted dogs (for example your neighbours annoying puppy).Read "Info" section in app to learn exactly how to use this app.That not all!We have bonus. The app is also a live wallpaper(set cute dog as a wallpaper) and widget (you can place direct link to this app on your home screen)This app may not give 100% chance of success in dog training. There are a lot of dog breeds in the world and each breed can have different hearing range.Moreover some of built-in phone speakers are not able to produce high frequency sounds.
