Funtons is an app that lets you manage all your funny sounds. You can download the sounds you want from the server, and they will be saved to your SD Card in Ogg Vorbis and MP3 formats. This way you will have only the sounds you want and will be free to do whatever you want with them.
You can search new sounds inside the application, get the latest and the highest rated. Even you can preview the sounds and change the button color.
The application includes widgets and a upload dialog to add the sounds you miss. Try it!
