Do you have a dog? Do you have an iPhone? If you answered yes to both of those questions, do yourself a favor and go download Dog Whistler. This simple app mimics the sound of a dog whistle as you press the whistle picture on your screen. You can adjust the sound range from 800HZ to 2200HZ, and even set four different presets. I am sure each dog will respond to different ranges, but my Pugs would immediately turn their heads at about 3100HZ and my border collie only perked up for 3400HZ. I don’t use a real dog whistle so I cannot speak to how well it really works in practice, but its a heck of a lot of fun to “blow” the whistle and watch my dogs freak out. Its also pretty interesting for humans too. I found my fiance could hear a lot farther up the HZ range than I could. The app looks great and the sound it emits is very clear and loud. Dog Whistler is a free app in the App Store and can be found with this iTunes link. Give it a shot and sound off in the comments if you had success using it “for real”.
