Reality television star Kim Kardashian’s latest mobile app is topping Apple’s charts, and could be her next big money maker. In December 2015, Kardashian expanded her empire of apps with a new emoji app, aptly titled Kimoji.

On Thursday, Kardashian updated her app with a slew of new emojis, as well as “KIMOGIF” animations, which feature short animations of the television personality hitting her sister with a Chanel handbag, and “making it rain” with $100 bills. Kimoji also debuted an Android version of the app in the Google Play store.

Kimoji, which costs $1.99, also now gives iOS and Android users access to 500-plus Kardashian-themed emoticons (up from 250 in the last version of the app), including emojis of Kim, her engagement ring, her lips, and even her infamous Paper Magazine “break the Internet” photo. People who download the app can use the emoticons—small cartoon-like images—with messaging apps like iMessage, WhatsApp, and Facebook Messenger.

Kimoji was produced and developed by Los Angeles-based media company Whalerock Industries, which previously created an app for Kardashian that gives fans an up close and personal look into her life. The company also developed similar apps for Kardashian’s sisters, Khloe, Kourtney, Kylie, and Kendall Jenner.

It’s unclear how these apps are performing, but Kardashian may have struck gold with her latest app.

Following the update on Thusrday, Kimoji topped Apple’s paid apps. The app also landed a spot in top grossing apps chart for Apple, with Kimoji’s app at number 45, just behind Kardashian’s hit mobile game, Kim Kardashian: Hollywood. Currently, Kardashian is the only celebrity with two money making apps in the top 50 of Apple’s top grossing apps chart.

Kardashian’s game, which was produced by Glu Mobile, has already brought in significant amounts of revenue. In 2014, the Kardashian game generated $74.3 million, or more than 30% of Glu’s total revenue. Kardashian gets a portion of that revenue. Estimates pegged 2015’s revenue at $200 million.

There aren’t any accurate reports yet of how much Kardashian is bringing in with her emoji app but there’s likely some sort of revenue share agreement with Whalerock, which also develops apps for musician Tyler the Creator, and radio personality Howard Stern.
