Ultra mosquito fear

Ultra mosquito fear is a joke app that lets you simulate an ultrasound device for repelling mosquitoes, spiders, and mice. Even though the app isn't able to kill these animals or insects, or even repel them from the room, you can make your friends and family think that you have in your hands an efficient tool for getting rid of pests.

The app is simple and the interface is user-friendly. It only has three buttons that will take you to the panel for each option. The first one takes you to the supposed anti-mosquito where you can see three more buttons that indicate the frequency of the sound that your device will play to drive them out of the room. You can select the option for 12 KHz, 17KHz o 20KHz to 'increase' the strength of the action. The other two buttons for insects and rats, are exactly the same and the sound they emit are exactly the same, too. You just might be able to convince your friends that your Android works as a pest repellent. Do you think you can pull off this prank?
