On Thursday 7 July, only a day after its surprise US launch, Pokemon GO was already installed on more Android phones in the US than Tinder.

While Tinder is installed on just over 2% of US Android devices, Pokemon GO had been installed on 5.2% a mere two days after its launch, according to SimilarWeb data.

Even more striking are its engagement statistics, which show that Pokemon GO is quickly gaining ground on Twitter in terms of daily active users - and, at its current rate, is expected to overtake it in a few days.

More than 60% of those who downloaded Pokemon GO in the US are playing daily, and at an average of 43 minutes, 23 seconds a day - higher than Whatsapp, Instagram, Snapchat, and Messenger.

However, it's worth noting that the buzz on social media has not been driven by the US alone.

This is because many outside of the territories in which the game has been officially launched have been taking to unofficial app download site APK Mirror to get the game ahead of time - resulting in the site's traffic exploding from 600,000 on 5 July to more than 4 million upon the launch of Pokemon GO.
