The youngest Kardashian sister is outpacing the rest of her famous clan when it comes to their new mobile apps.  Kylie Jenner’s app was downloaded 1.75 million times during the first week of availability, according to mobile app data firm Apptopia. In contrast, Khloe Kardashian’s app had 498,000 downloads while Kim Kardashian’s app saw 477,000.  The apps, produced by LA-based media company Whalerock Industries, premiered last week along with the inevitable tabloid frenzy. They are intended to give fans more of an up close and personal look into each of the sister’s lives through photos, videos and live-streaming — and, of course, make them some money.  In beating her sisters, Kylie, 18, shows that she packs some considerable star power, especially with younger people. She’s gained a massive interest on social sites like Snapchat and photo sharing app Instagram, where she has 36.5 million followers.  Whether that following that can translate into millions of dollars for the reality TV show starlet is less certain. Kim and Khloe, also stars of Keeping up with the Kardashians, have established a career beyond television to include event appearances and fashion lines.  The apps came with a seven day free trial, so they haven’t had much of a chance to sign up subscribers willing to pay $3 monthly. But on Monday, after the initial batch of download trials ran out, they appear to have had some success.  Kylie’s app brought in $134,000, according to Apptopia, compared with Khloe’s app, which brought in $25,000. Kim’s app brought in a little more than $19,000.  Khloe Kardashian’s app topped conversions with 9% of users opting to pay for the app after the trial. Kim’s app followed with a 7% rate, followed by Kylie with 6%.  Apptopia projects that Kylie’s app will bring in over $400,000 in sales in the first week, nearly three times the $150,000 that Khloe’s app is expected to earn.  But just because Kylie is on track to bring in hundreds of thousands of dollars in revenue, it doesn’t mean it’s all hers. Apple reportedly takes a 30% cut from app downloads. There’s also a financial agreement with Whalerock, but the terms are unclear.  Whalerock declined to comment to Fortune for this story.  In addition to the apps, the Kardashian and Jenner sisters all have individual websites that also charge $3 monthly. The revenue data from Apptopia does not include those web subscriptions or any cut from advertising and from e-commerce on the apps.  This isn’t Kardashian West’s first brush with success with mobile app. Kardashian’s hit mobile game, Kim Kardashian: Hollywood, raked in $74 million last year.
