Google at its I/O 2016 event in May introduced two apps, Allo and Duo, both of which it promised will be available during summer. The company has officially launched the Duo app and it is now available for Android and iOS devices. The Allo, however, is yet to surface.
The Google Duo is a video-calling app that enable users to connect and interact with family, friends and loved ones in real-time. Unlike other Google suits of product, the app does not requires Google ID in signing up, all that is needed is a verified phone number. After logging in, an user can view other active users on his/her contact list (just like the “Contact” menu on Whatsapp). To start a conversation, the user will tap on an active user on his/her list and the app will initiate a connection.

According to Google, the Duo app uses end-to-end encryption to protect users privacy and data. Another notable feature is Knock Knock, this allow users to preview incoming calls before they answer it. Video call can be made using a WiFi or a cellular data, and when Duo sense a weak connection during video-calling on one network, it automatically switch to the other to keep the call going. In addition, the app will auto tune-down the resolution of video call when it sense a limited bandwidth.
