All of the Kardashian/Jenner sisters are making huge money from their new iPhone apps, but Kylie leads the line with more than one million downloads.

With some considerable star power Kylie outpaced her well-known sisters, Kendall, Kim and Khloe Kardashian in terms of app downloads and proceeds. Kourtney did not launch her official app yet.

Kylie's app worth $3 a month was downloaded 1.75 million times during the first week of its launch, according to Apptopia, which specializes in mobile app market intelligence.

Khloe's app had 498,000 downloads while Kim's app had 477,000. The apps are intended to give the fans a more personal look into each of the sister's lives through photos, videos, and live-streaming.

Kylie, 18, gained a huge fan following on social sites like Snapchat and Instagram, where she has 36.5 million followers. This fan following of the star of "Keeping Up With The Kardashians" could be transformed into millions of dollars.

The apps came with a seven-day free trial. Kylie's app brought in $134,000, compared with Khloe's app, which brought in $25,000. Kim's app brought in $19,000.

Khloe's app topped conversions with 9 percent of users opting to pay for the app after the trial period. Kim's app followed with a 7 percent rate, followed by Kylie with 6 percent.

Apptopia anticipates that Kylie's app will bring in over $400,000 in sales in the first week, approximately three times the $150,000 that Khloe's app is expected to earn.

The apps, produced by LA-based media company Whalerock Industries, launched on Sept. 14 along with the anticipated media frenzy. Apple reportedly takes a 30 percent share from app downloads. There's also a financial agreement with Whalerock, CNN reported. 

The reality TV show starlet has successfully ventured into many businesses earlier as well. In 2012, Kylie collaborated with the clothing brand PacSun, along with her sister Kendall, and produced their own clothing line "Kendall & Kylie."

Their sci-fi novel, "Rebels: City of Indra," was released in 2014. Time magazine named the Jenner sisters in "The 25 Most Influential Teens of 2014" for their considerable influence among teens on social media.

In June, the Jenner sisters launched their clothing line "Kendall + Kylie" with British fashion retailer Topshop. On Aug. 18, Jenner announced she will be launching her first lipstick line as a part of her self-titled lip kit.
