NEW YORK • 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 US$1.99 (S$2.74) Stephmoji keyboard went on sale on Wednesday afternoon and, by Thursday morning, was the best-selling paid app in Apple's store, beating Kim Kardashian's emoji and the mobile version of Minecraft.

The app features the 28-year-old in a variety of poses, including shooting from the moon, clutching his Most Valuable Player trophies - he has two - and chewing on his mouth guard, a classic Curry tic.

However, the Cleveland Cavaliers' LeBron James is winning on social media - some 31 million people follow @kingjames on Twitter alone, more than Curry's Instagram (11 million), Facebook (six million), and Twitter (five million) fans put together.

James also makes more money - US$22 million this season, twice Curry's US$11.3 million - though he does not have his own emojis.
