'King Kylie' Jenner Rules iTunes, Beating Sisters' Apps

Reality star Kylie Jenner is the most popular in the Kardashian/Jenner clan, at least according to iTunes.

This week, Kylie, Kim, Kendall, and Khloé each launched their own apps, which allow users to gain access into their world for $2.99 a month.

Community.com's Alaxic Smith researched all four sites and found out the number of subscribers on each app. Of 891,340 users who signed up on the first day, Kylie dominated with 74% of the subscribers, Khloé was second with 11%, Kim had 10% of the subscribers, and Kendall had 6%, according to TMZ.

So many people were subscribing to Kylie's app that it crashed! Kylie warned her fans, tweeting, "Ok update: there's a lot of people on the app so I'm sorry if it's freezing for some of u guys! It's being fixed and it will only get better".

Once the app hit the top spot on iTunes, Kylie wrote on Instagram, "#1 I can't believe it. I love you guys. Can't wait to post more tomorrow." There's a reason why she calls herself "King Kylie!"
