Have you heard that expression before?
“Killer app”…?
It describes an application / piece of software that is so valuable or useful you want to buy the computer just to be able to use it.
The first killer app was a program called “VisiCalc.” It was a finance spreadsheet that saved accountants a lot of time. Before this program was invented, an Apple computer was bought for fun. But after this killer app came out, people bought the computer just to use the app.
