A free app for Android, by Nordeck Interactive.

You can now fart using your Android Wear watch or smartwatch! In order to do this, you will first need to download the application on your phone. The app is free and has no ads or in-app purchases. You will be able to select the fart you want to use and record it. You can record farts from the device or use the ones you record in the application. The application also has two modes of control: the first one is turning on the "Whoopee Notification" on the phone, and the second is using the "Whoopee Wear" application directly on the watch.
