Johnoise is a soundboard of "John," an alter ego that anyone can use to express themselves comedically. Johnnoise includes a wide range of affirmations, greetings, and questions. Each sound is generic and applicable to many different scenarios.
The app features just a single view: a scrollable list of buttons and labels, each corresponding to a unique sound. A cartoonish depiction of the boisterous "John" is displayed at the top of the screen and is also features as the apps icon.
