Emoji have become a big digital business for Hollywood celebs.

Actor-comedian-entrepreneur Kevin Hart’s new emoji app for Apple iOS devices, launched Tuesday, shot to the top spot on the App Store’s paid-apps chart within five hours of its release, where it currently still sits. Hart has been actively promoting the $1.99 app on social media, where he has nearly 100 million followers across platforms, and Apple currently is featuring “Kevmoji” is the App Store’s “new apps we love” section.

The hot debut of Hart’s emoji app comes after other celebs, including Ellen DeGeneres and Kim Kardashian West, have seen success with their own branded emoji keyboards.

Kevmoji is one of the first emoji apps to feature real faces (of Hart, of course) and real video-based GIFs, and offers stickers, sound bites and a QWERTY keyboard. The app is integrated with Apple’s new iMessage app for iOS 10, and for 99 cents extra users with iOS 10 can unlock additional animated Kevin Hart heads to send to their friends. It’s slated to be released for Android devices soon, as well.

“When we decided to make Kevmoji, all I knew is that we had to do something no one else was doing,” Hart said in a statement. “So here we are, literally changing the face of iMessage by creating a real experience through emojis and stickers, rather than in animation.”

Hart, who starred in action-comedy “Central Intelligence” with Dwayne Johnson this summer, also is expanding his digital footprint with internet video network Laugh Out Loud, slated to launch in 2017 in partnership with Lionsgate. He’s repped by UTA, 3 Arts Entertainment and Schreck Rose.

In Apple’s App Store, Kevmoji is rated for users 17 and older, because of “infrequent/mild sexual content and nudity,” mature themes, frequent profanity or crude humor, and mild alcohol, tobaccor or drug references.

Hart’s HartBeat Digital developed the Kevmoji app in partnership with Snaps, a New York-based provider of brand-marketing mobile messaging solutions whose clients also include Burger King, Viacom, Pepsi, L’Oréal USA and Unilever.
