Fortnite is undoubtedly one of the most popular games on Earth right now. The game has been available on all gaming platforms, but it seems that the bulk of its profits are coming from players on mobile. 

Although Fortnite is a free-to-play game on mobile, the game's profit comes from microtransactions. According to a report by mobile analytics company Sensor Tower, the iOS version of Fortnite was able to rake in an average of $2 million per day over a 10-day period after the launch of Season 5 this month. The figure is a slight increase from the game's reported daily average of $1.2 million since its start in iOS on March 15 until the end of Season 4 on July 11. 

Furthermore, Sensor Tower also reported that the game reached an average of $3 million daily, which is a new record in the history of the game. This figure is a considerable increase, from the previous record amounting to $1.9 million on May 1 for the start of Season 4. 

Moreover, Sensor Tower estimates that the game has already brought more than $150 million in revenue from just the mobile version alone. It is worth remembering that Fortnite's mobile profits are only from the iOS version as the Android counterpart is still yet to come.
