Relax! This is not an online quiz that tells you which app you have a match with. The idea is to get you to think about what kind of app you are building.
From a discovery standpoint, we do see apps get slotted in different categories - business, productivity, entertainment, games, news, social, commerce, etc.
For those of us building mobile apps, it probably also helps to think about how to slot your app from a different angle - "what's the interaction / engagement model of this app?"
