Some call it a "dog whistle", while others call it "annoying". There are producible sounds that dogs can hear which humans can't, but did you know that there are sounds that only specific age groups can hear? That's right, you can now drive your little brother crazy with this app. You can even play these sounds in class and annoy everybody in the room except the teacher (although not suggested). Ultimate prank: connect your device to load speakers at a party and have all the kids freak out except the adults.
Frequencies Pro plays fifteen different frequencies ranging from 8 kHz, which can be heard by mostly everyone, and 22 kHz, which can only be heard by children under 13 years old.

Frequencies Pro plays fifteen different frequencies ranging from 8 kHz, which can be heard by mostly everyone, and 22 kHz, which can only be heard by children under 13 years old.
Frequencies Pro also has a "pulse" feature, which plays frequencies in a way that is noticeable by playing the frequencies in a pattern, like repeated beeping noises, instead of playing the frequencies continuously.
Are you a high school student? Frequencies Pro also allows you to choose your target based on their high school grade level. Annoy the Freshman... their the most gullible...
Have pets? Frequencies Pro can get their attention by producing a 22 kHz tone, which can be heard only by small children and most animals, like cats and dogs. What? You thought that these frequencies can only be heard by dogs? Almost all mammals have better hearing than us. We can only hear up to 23 kHz, while dogs can hear up to 45 kHz, cats up to 64 kHz, and rabbits up to 42kHz, and so on.
One more feature that Frequencies Pro has that similar apps do not is the ability to play these sounds while the screen is locked or with the silence switch on. So you can start playing a sound on your device, turn the screen off, and walk into class with it in your pocket! Because of it's very high pitch, the source of the sound is very difficult to locate, yet still very annoying; nobody will know it's you, unless, of course, you're the only other person in the room.
*Warning*: Playing sounds for more than five minutes could possibly damage your device's speakers. Please do not leave the frequencies playing, as we have not added a playback duration limit.
