When it comes to K-apps, Kylie is queen — by far.

The famous selfie-loving Kardashian sisters are on track to make $25.5 million this year from their most recent project — personalized apps that feature everything from makeup tips to details about their personal lives.

The $3-a-month apps, launched Sept. 14, are among the best sellers in Apple’s App store.

The youngest sister, Kylie, was the eighth-highest-grossing app on Tuesday.

Kylie’s app is projected to bring in sales of up to $400,567 in the first week, according to Boston-based app-measurement firm Apptopia. After a free week, the app started charging on Sept. 21.

A Kourtney Kardashian app is in the pipeline, according to sources.
