Google Duo is one of the highest-quality video calling apps for Android users developed by Google. It’s very simple, straightforward, and highly reliable. It also shows a preview of the caller so you can see it before answering the call.

It’s also a cross-platform app available on Android and iOS platforms. Google also developed a web version of the app for PC users but with limited functionalities. This app is also free and has an end-to-end subscription for safety and security purposes. How do you use Google Duo? It is discussed in this article.
