Los Angeles media company Whalerock Industries has created a new app for Kim Kardashian that is proving so popular it prompted the reality star to tweet that demand for downloads had slowed service at Apple’s App Store.

The new emoji app, called Kimoji, gives iOS users access to 250-plus Kardashian-themed emoticons, including emojis of Kardashian, her engagement ring, and her lips, among others. According to Fortune, the app, which costs $1.99, was the top downloaded paid app in Apple’s app store on Monday.
