Fortnite iOS launched last week and players spent $1 million on in-app purchases within the first 72 hours. According to data from Sensor Tower, the game has raked in over $1.5 million worldwide so far, which is impressive, considering the release has been limited to invite-only on iOS. Sensor Tower reports that, based on cosmetic in-app purchases alone, Fortnite has grossed around a third of the revenue that Pokemon Go earned in its first four days on iOS.
