Anti Mosquito - Sonic Repeller

I used to install mosquito repellent applications with sound, but they didn't work. This is the first time I find it effective, really effective and I am pleased with this application.
This application is suitable for IOS, I see a similar application for Android but not sure if it is the same application, because the logo is a bit different. Therefore, I only to link the application to IOS.

Not only mosquitoes but also chasing some other insects. Of course, you cannot ask too much for the application because there are more than 3500 species of mosquitoes, that is, some types of mosquitoes will not be chased away.
You will almost never be able to hear the sound from the application. Unless you bring your phone close to your ear.

The thing I am not happy with in this app: It doesn't run in the background, you have to open the app and hang it to work with the screen always on.

Now enjoy your wonderful moments without being bothered because It is free.
