Kylie Jenner's new mobile app is bigger than Facebook, Instagram and Snapchat and even bigger than apps from other members of the Kardashian-Jenner clan.

Kylie made it to the top of the Free Apps chart while her sisters Kendall Jenner, Khloe Kardashian and Kim Kardashian lagged behind although their apps were successful as well, according to Complex.

Some users are happy with the new app. "@KylieJenner this app is the best thing you ever did, I'm loving the radio," one user tweeted.

Another replied, "Once your 7 day free trial is over we'll see if you still love it!" Are there any issues with the app once the free trial is over? Or are people just hopping on the band wagon because it's free for a week?

Although the other members of the Kardashian-Jenner clan did not make it to the No. 1 spot for the most popular free app, they still made top 20, NBC News notes. Khloe was No. 8 as of Wednesday while Kim made No. 11 and Kendall made No. 16.

The app costs $2.99 a month after the free trial is up. In each app, users get a personal diary-style behind-the-scenes look into the Reality TV stars' lives.

Kim K made millions of dollars with her mobile game "Kim Kardashian: Hollywood" last year. Will the personal apps prove to be just as successful? Let's see how many users will subscribe once their free trial is up.

Meanwhile, Kylie's fame has continued to grow since she turned 18 and finally confirmed the rumors about dating 25-year-old rapper Tyga. Reports say the couple has been on the verge of breaking up lately because of constant arguing.

Sources say Tyga wants Kylie to settle down and enjoy life a little bit, however she wants to work every single day and constantly build on her brand. As you can see, her app proved to be very successful.

The Kylie app was developed by Whalerock Industries.
