Just two days after it first began to roll out, Google's Duo has already become the number one free app in the Play Store. The video chatting app, which received an icon redesign just before it went live, has proven to be extremely popular with Android users. In addition, it is now possible to use Duo in any country (well, any country that Google provides its services to).

Google Duo now launched in all countries. #1 app in the Play Store, 4.5 star rating! 🎦📈🙌 pic.twitter.com/hbN09ku20k — Justin Uberti (@juberti) August 18, 2016

Justin Uberti is Duo's technical lead.

In the Play Store's "Top Free in Android Apps" chart, Duo currently sits in the top spot, ahead of other free apps such as Facebook Messenger, Pokémon Go (is that still a thing?), Facebook (for God's sake, fix your Android app), Snapchat (code it correctly, dammit), YouTube Music, and Instagram. It's entirely possible that this is just a temporary surge, but it's nice to see that people are demonstrating interest right now.

Although people in countries other than the US and Canada were originally unable to verify their phone numbers through SMS, that's been fixed. Support for more countries gradually rolled out over the past two days, but the global rollout has just now finished. Now, anyone with an Android device running 4.1+ can enjoy Google's new video chatting app, regardless of their location. And enjoy it they will, according to Rita's review.
