Just how popular is Fortnite? Let’s help you with that. In the first 3 months that it was on Apple’s App Store, the wildely popular game raked in over $100 million USD. The game is free to play, but the earnings came from in-app purchases of cosmetics and battle passes that offer exclusive rewards. It is the third most successful mobile launch ever. Clash of Clans still holds the record at $154 million USD in earnings for its first 90 days on mobile.
