There's no need to panic about Pokemon GO. Though you're almost certain to have read articles in various places about how it has fallen off in terms of popularity since its stellar debut, that was inevitable. When your star burns as bright as Pokemon GO's did, literally the only place to go is down.
The numbers tell a slightly different story. Pokemon GO is still a top 20 app as we head into the holiday weekend in the U.S., even bouncing up a spot from the previous chart. That's not too shabby for a game that's been out for two months.
More importantly, it's still the top grossing iPhone game (though unlike some of its competitors for that throne, it's way further down on iPad). That should give Niantic all the resources it needs to keep plugging away on updates.
And make no mistake, those updates are definitely needed.
