Applications or "Apps" are programs written by a person or a company for a specific reason.
The most popular use of apps would be in the iPhone, or the Android phone.
For example, my iPod Touch had an app that ran an E-book reader, which allowed me to read books on my iPod when I normally wouldn't be able to.
As for how they work, im guessing they are coded like any other program, and I dont really see why they are bad at all, so I cant answer that
