Fortnite isn’t just winning over celebrity fans, it’s also making money.

As I reported earlier today, Fortnite is the No.

2 highest-grossing game on iOS, and app store intelligence firm Sensor Tower estimates it has made $1.5 million worldwide on Apple’s devices since turning on in-app purchases.

Sensor Tower mobile insights boss Randy Nelson notes that more than $1 million of that total came in the first 3 days that the app was available on iOS.

Fortnite is in an invite-only period on mobile, so people cannot just download it and start playing.

Those revenue numbers could see significant growth once Epic opens up Fortnite to everyone on iOS and then Android.
