Kylie Jenner's App Goes to Number One, Tops Her Sisters

Kylie Jenner puts her hand over her face while leaving the Trump Hotel with her boyfriend Tyga on Tuesday evening (September 15) in New York City.

Kim and Kourtney Kardashian were also seen all dressed up that evening while heading out to dinner.

Kim, Kylie, Khloe, and Kendall all launched their brand new apps the day before and the clear winner is Kylie, whose app is still at number one in the iTunes app store.

“I love my radio feature on my website!!! All my favorite music.. Always updating!” Kylie tweeted. “All I do all day is listen to Kylie radio.”
