Kylie Jenner Destroying Kim, Kendall and Khloe Online

According to the CEO of communly.com, Alaxic Smith, who unearthed subscriber numbers for all the apps, Kylie is ruling the game. She even beats Instagram, Facebook, Twitter and Yahoo Messenger.

The numbers are staggering ... 891,340 people signed up for the four sites within 24-hours and here's the breakdown:

74% KYLIE

11% KHLOE

9% KIM

6% KENDALL

Smith says the loophole that allowed him access to all the subscriber info has now been closed ... not that it matters, because Kylie's already popping off on IG about her #1 status.
