In recent months, it seems like every famous person has an app. From the Kardashians to Steph Curry, they've all got at least one. But why are they all jumping on the app bandwagon? It's because the business of apps is extremely lucrative. Celeb apps are created with two things in mind, personal brand expansion and money. When you download a famous person's app, they have essentially integrated themselves into your everyday life. Your phone is a means for them to interact with you while promoting their brand on a more personal level. Most people use their phones everyday in one form or another, whether it be checking emails or downloading apps, using our phones have become an important part of life and famous people are taking notice.

Many celebrities promote their apps or games as "free", this is true for the most part, but there's a catch. From the moment you download an app onto your phone, you become a number. Apps generate money from the number of installs they have and there is always some form of a store where you can purchase "packs" or "bundles" for a low price, this is called free premium or freemium.

Vox news reports, "The first thing these games do is set up a virtual currency, so it doesn't feel like your'e spending real currency even though you are. This is a variation on something we've known for decades, which is that people find it harder to spend money when they're paying in cash, than if they're using a card."

The truth of this argument is evidenced in a statement from author Jamie Madigan, he notes, "When you pay cash for something, you see it leave your hands and you get a very immediate sense of how much your cash reserves have dropped, how much your wealth has dropped."

Games and apps not only distance their associations with spending money, they also don't make the exchange rate simple. Madigan notes, "There's always something weird, like $1 equals 12 purple diamonds and that sort of off-kilter exchange rate is the same thing as when you see people like tourists spending money that they're not familiar with in foreign countries."

While using these celebrity games or apps, you spend money that does't seem real because the actual purchase is so far removed from the experience that you don't associate it with spending money.

Vox news reports, "You're spending money that doesn't seem real and it only takes a second because the app store already has your credit card. The whole payment process is designed to be painless."

So, the next time your'e scrolling through your Instagram feed and see a famous person promoting their app, maybe think twice before clicking the link in their bio.
