Pokemon Go is beginning to see a decline in popularity, losing several million players over the past week.

According to Survey Monkey, Pokemon Go had 25 million daily active users on July 14th, but by July 20th, that number had declined to about 22 million.

This 22 million number is still far more players than the game started with, however, as it received roughly six million daily active users upon its launch on July 7th. But this data suggests that the game may have hit a peak in popularity, and it has been on a steady downward slope since July 14th.

In addition, Google searches for Pokemon Go peaked between July 13th and July 15th, but this search interest has been in decline as well.

All of this doesn’t necessarily spell crisis for Pokemon Go. Some drop was to be expected considering just how massive a phenomenon the game became within the first two days of its launch, as compared to other mobile games which take a significant amount of time to gain steam. Not all of these players were guaranteed to stick with it, and over 20 million daily active users is still an incredibly impressive amount for a game released by a studio with fewer than 50 employees.

But some fans are worrying that this spells the beginning of the end of the Pokemon Go hype train and that many casual players are quitting the app in frustration due to the sheer number of game-breaking glitches. Over the period of time that this decline in popularity took place, the game was riddled with server crashes and bugs that caused the app to freeze or made it very difficult to catch Pokemon.

One Reddit user observed, “Most of the casual players have quit because they got tired of a game that never works eating their battery. They’ve stopped scheduling time to go into town for Pokemon hunting.”

Others on Reddit chimed in to say that in their area, the game is almost completely dead now, with nobody bothering to defend gyms anymore.

But the game’s developer, Niantic, recently assured fans that they’re working on the issues and that they plan to provide frequent updates to the game in the same way that an MMO does. Niantic also teased updates to Poke Stop customization as well as the addition of new Pokemon, according to Comicbook.com.

“There are a certain set of Pokemon in the game right now,” Niantic CEO John Hanke said. “There are some rare ones that haven’t showed up yet that will be showing up. And there are some other ones in the universe, it’s something we’re excited about continuing with in the coming years.”

As soon as a major update is released, and as soon as some new content begins rolling out, it’s highly possible we’ll see a massive bump in players again and that this decline in enthusiasm could prove to be temporary.
