Just two short days after launching their eponymous apps, the Kardashian and Jenner sisters have already achieved total iTunes domination. The question, of course, is which one has summited to that elusive No. 1 spot? We'll give you one guess. Yup, it's Kylie. Or, as she likes to call herself, King Kylie. The youngest of the clan is officially the most popular, app-wise. The Kylie Jenner Official App was at the top of the free app chart two days ago, a feat Jenner celebrated with an Instagram post thanking fans. "#1 I can't believe it. I love you guys. Can't wait to post more tomorrow," Jenner wrote alongside a screenshot of the iTunes chart, in which her app topped both Facebook and Instagram. On September 15, Khloé Kardashian exuberantly tweeted that the family's apps were holding court at the top four spots in the free category of the iTunes store. Please note that she had yet to download Kylie, Kim, or Kendall's apps. Maybe she did it after tweeting. As of this writing, Kylie's app is still at No. 3 on the free apps chart. Kim Kardashian West's app is No. 32, while Khloé Kardashian's is No. 33. Kendall Jenner's app sits at 48. Kourtney Kardashian's app, which has a mom focus, isn't in the top 100. An ONTD writer took on the task of reviewing the Kylie Jenner App, summing it up thusly: "Kylie's $44.99/year app [there's a free trial version, but after seven days, you're charged $3.74 per month] offers very little; asks for too much." The app is divided into three sections, "Radio," "Looks," and "Lyfe," (if it's spelling lessons you're after, you should probably look elsewhere), and the ONTD user plowed through the majority of the app's content after 10 minutes. In the meantime, Kylie Jenner has dyed her hair green and appeared in her brother-in-law Kanye West's Fashion Week presentation. In other words, the world continues to turn, and the Kardashians and Jenners continue to live their lives, infiltrating ours with their #brands. Think happy thoughts, everyone.
