On Monday, September 14, most of the Kardashian/Jenner sisters launched apps: Kylie, Kendall, Kim, and Khloe (RIP Kourtney). Each program purposefully differed enough to give the user an inside look at each woman and her individual personality for the low, low price of $2.99 a month. 

Surprisingly enough, it was Kylie's app that garnered the most attention...within a few minutes of launch, too many people were flocking to it, shutting the thing down. It sort of makes sense that hers would be the most popular: She's probably the most social media savvy of the bunch, and she's also the youngest—the same (teen)age as the most avid mobile users.

It gets better: MTV reports that the app was downloaded more than Facebook and YouTube in the last, like, forget beating your sisters. KJ is besting massive billion-dollar companies!
