The Pokémon Go shows that the popular game isn’t only the biggest in U.S. history – it’s also breaking records when it comes to its ability to monetize and retain its users, as well. Pokémon Go is seeing retention rates at more than double the industry average, and is pulling in revenues at twice the average rate for casual games.

The news follows earlier reports this week from a number of tracking and analytics firms which painted a picture of the app’s viral spread and significant traction.According to SimilarWeb, for example, the app passed Twitter in terms of daily active users on Android as of Monday, while another report from SensorTower said that users were spending more minutes per day in the Pokémon Go app than they were in Facebook.

SurveyMonkey estimates that just under 26 million U.S. users played the app on iOS and Android on Thursday, which is “unprecedented” for a mobile game, it says. Plus, more people are using the maps in Pokémon Go, which are powered by Google Maps, than they use the Google Maps app itself.

Right now, Pokémon Go is rapidly finding its way onto new devices at a rate of 4 to 5 million installs per day, but this pace can’t continue forever, of course. That’s why looking at the app’s ability to retain its users is also important. So far, Pokémon Go is succeeding on this front as well, though it’s still early days.

It seems that even the mildly curious are finding themselves immediately addicted. Around 7 out of 10 people who download the app return to it the next day, the report says. That’s extremely high for the industry – typically, games see 3 out of 10 people returning after the first day.

In other words, Pokémon Go is seeing more than double the industry average retention rate for the time being.
