On the contrary, Whatsapp provides you with a list of your chats as you open the application. Now, you can either click on any of the chats and start a video call or simply swipe to the calls tab and make a call to whomever you want.
For any reputed app, one of the main USP behind their popularity is their cross-platform availability. Luckily, both Whatsapp and Google Duo is available across most of the major platforms, including iOS, Android, and even for PC/Laptop. However, Whatsapp doesn’t allow video calling on desktop, unlike Duo. But it provides desktop clients for Windows as well as Mac, whereas Google Duo is available only in the web version for desktops.
App Features

Whatsapp is a one-tier platform satisfying all your communication needs. In here, you can send text messages, voice calls, and video calls too. The app offers centralized control over all your conversations and further allows you to share images, videos, and other files.

On the other hand, Google Duo is specially designed for video calling. Besides, you can also send temporary messages that last for the next 24hours, which is more like the Whatsapp status. It supports different formats like recorded video or audio, or simply a note containing your message.
Video Calling Experience

Coming to the most important part, the video calling experience in Google Duo is far better than that of Whatsapp. This is because it’s easy and consistent user experience. Google Duo offers a much better interface for video calls, and the quality is, of course, pretty impressive.
In case you are having a low internet connection, Google Duo can still manage its video quality up to an extent. While you might face “Poor Connection” alerts in Whatsapp, causing the video to pause in middle. This actually brings one of the most noticeable differences between the video calling service of both these apps.

Apart from that, when it comes to group video calling, Whatsapp only supports 4 users at a time. But in Duo, you can add up to 12 people in a group call. Plus, each group is saved in your account so, when you make a call the next time, you don’t have to keep adding them again and again.
Video Calling Filters

Adding cool filters while video calling seems fun. Surprisingly, Google Duo offers some really amazing effects which you can add while on a video call. There is a bunch of fun and interesting collection in the Effects and Filters option in Duo.
However, this thing is missing in the Whatsapp video call feature. Here, you can simply start a normal video conversation with your friends or family. There is nothing much interesting about the video calling option in Whatsapp as compared to Duo.
Conclusion
Hence, all these things make Google Duo a more refined video calling app. Although Whatsapp offers a bundle of other features, which makes it a complete app for holding conversations. But in the Google Duo vs WhatsApp, Duo nails it in every aspect. It offers several attractive features and much reliable service than Whatsapp. Let us know which one you think is better among these two, or if you have any other suggestions.
