Steph Curry's $1.99 emoji app is crushing Kardashian, Minecraft

Stephen Curry's social media following extends to more than 20 million fans, more than enough to make the guard's new app a top seller in less than 24 hours.

The $1.99 Stephmoji keyboard went on sale Wednesday afternoon and, by Thursday morning, was the best-selling paid app in Apple's store, beating out Kim Kardashian's emoji and the mobile version of Minecraft.

The app features the 28-year-old guard in a variety of poses, including shooting from the moon, clutching his MVP trophies - he has two - and chewing on his mouth guard, a classic Curry tic. There are also emojis featuring his wife, Ayesha, a host on The Food Network, and his daughter Riley, who became a media darling during last season's championship run.

Curry's Golden State Warriors play LeBron James's Cleveland Cavaliers tonight in a rematch of last year's NBA championship. While the Warriors won last year and Curry is this season's consensus MVP, James is winning on social media: Some 31 million people follow @kingjames on Twitter alone, more than Curry's Instagram (11 million), Facebook (6 million), and Twitter (5 million) fans together.

James also makes more money - $22 million this season, twice Curry's $11.3 million - though he doesn't have his own emojis. Curry is a free agent after next season.

Major League Baseball during last season's playoffs began MLB.com Clubhouse, where fans could customize personal keyboards with stickers of their favorite teams and players. And the NBA created emojis for all its All-Star players this season, activated by using hashtags of the players' names on Twitter.
