Pokemon GOhas been number one on the App Store top grossing charts in the US twice since its decline began in September 2016.
Based on App Annie's data, the game initially dropped to second place on September 19th. Since then it has returned to the top spot on both September 24th and October 2nd, where it held position for two days.
The September 24th leap coincided with an update to the game, which would explain why players returned to the game to spend.
The October jump does not coincide with any update. This suggests that the game has now firmly reached its plateau, and will be seen jockeying for position with the other top apps from here on.
The game has been jostling for top position with other heavy hitters such as Mobile Strike and Clash Royale.
Beyond the US
In the UK, the game has remained at the top of the App Store grossing chart for 90 consecutive days.
It continues to be relatively suffering in Japan, where it dropped down to number 10 on the App Store top grossing chart on October 1st, but has since climbed back to 5th.
Fluctuations in the top grossing charts are to expected as the game settles down for the long-term. It's still performing remarkably well, generating a reported $2 million a day in revenue.
