Let’s Introduce

Before Starting with the Comparision let us know a Little about Both the WhatsApp and Google Duo.


WhatsApp is a messaging and Voice over IP application owned by Facebook, Inc. It was launched in 2009 but in 2014 it was acquired by Facebook for US$19 billion.

Being the most popular instant messaging app, it is able to carry out some decent video calls as well. Although the quality is still not up to the level that Duo is able to offer, the fact that WhatsApp is currently being used by every Android and iOS user really make it an easy app to go for. Also, its presence across all the platforms makes it a very palatable application for making video calls.

Google Duo

Google Duo is a mobile app used for video chatting developed by Google. It was announced at GDC (Google’s Developer Conference) on May 18, 2016, and officially launched on August 16, 2016.

Google and messaging, apps didn’t always seem to go hand in hand. Google tried many messaging services from the likes of Allo to Hangouts. But most of the apps have either failed or had only limited popularity. But this stance changed with the launch of Google Duo, a free video calling platform. This video calling platform from the Silicon Valley giant is probably the best app in its domain. Be it one-to-one or group video calls, be it on Wi-Fi or even cellular data, a stable and crystal clear performance is on the cards. Moreover, at a particular point of time, you could add up to 8 people on a single video call.
