Along with AI-based messaging app Google Allo, the company also launched the video calling app called Google Duo. Just like Allo, Duo doesn’t need Google account; you can directly connect with another user with the mobile number. The one-to-one call video call uses very small bandwidth and also performs better with slower data connections.
What makes the Duo standout from the other video calling apps is the end-to-end encryption and Knock Knock features that show the live preview of the caller even before picking up. The app offers HD video (1280 x 720 pixels) resolution and crisp audio. As of now, there is no group calling support, but we guess the company may bring with the upcoming updates.
The app is about 5MB in size and shows the live preview from the front camera when the app is opened. The circular contacts can be swiped up from the bottom of the screen. It also switches between Wi-Fi and mobile data without interrupting the ongoing video call. Both the Allo and Duo will be available within the next couple of months.
The simpler user interface of Duo makes it better recommended than the Apple’s FaceTime that additionally requires Apple ID. Users can use either of the rear or front cameras and can even change in between the call. Even Whatsapp is said to offer the video calling option soon for both iOS and Android users. The video calling option is recently found on one of the beta update for Android.
