The coolest prank app is here ! Bad Breath Analzyer works like a breathalyzer. Press Start and blow at your iPhone's bottom right corner. This app will appear to collect sample of your breath, then performs an analysis and shows you the results.
The result shown can be predetermined, depending on which area of the Start button you pressed ! Now, you can make your friends think their breath stinks, while yours is fresh as mint !
All results messages and app name in the main screen is customizable, so you can turn this app into all kinds of tester/analyzer, such as: flu virus detector, chocolate breath detector, etc.
Note: This app does not really collect and analyze breath samples. It is only made to appear as such for prank purposes.
