It became the top grossing app in the iOS app store, and was the most downloaded app within its first week ever.

But here’s another reason to be impressed by the augmented reality game’s rise—and a testament to its popularity.

SurveyMonkey compiled a list of the 30 most downloaded apps in the first half of 2016. They discovered that the most people downloaded Facebook Messenger in those six months, with 59.7 million downloads, followed by Snapchat with 54.5 million, and Facebook with 45.8 million.

Meanwhile, in the 22 days since its launch, Pokémon Go managed to clock in an estimated 50 million-plus downloads in the U.S. alone, according to the most recent estimates from Sensor Tower.

That means Pokémon Go’s downloads in three weeks exceeded that of Instagram’s 40.4 million and Youtube’s 22.9 million over six months.

The runaway hit, which has hit the top spot in charts across the world, was not included on SurveyMonkey’s list since it was released July 7 in the US.

But many are wondering if Pokémon Go is just a passing fad. The app’s daily active users seemed to have peaked at 25 million on July 14, according to SurveyMonkey. Then on Thursday, the app fell to the number two spot on Apple’s top free app chart, with Bitmoji Keyboard claiming number one.
