Meet DUO Best video calling app
This video calling app Designed for iOS and Android, Duo is being billed as “a simple, fast one-to-one video calling app for everyone”. Based on your mobile phone number like Allo, the app has a minimalistic user interface which fades away when you’re in a call.
Most of us hate answering calls, and that typically includes video calls. Duo wants to provide you with instant context by showing you the video feed of the other party before you ever answer — giving you instant context to decide if it’s worth talking to your drunken friend at 3am.
One of our favorite features of Duo is Knock Knock, which shows you a live video preview of the caller before you pick up. Knock Knock invites you into the moment, making calls feel spontaneous and fun. Once you answer, Duo seamlessly transitions you right into the call.
Duo is a simple, fast one-to-one video calling app for everyone—whether you’re on Android or iOS, a fast or slow connection, in New York or New Delhi. Like Allo, Duo is based on your phone number, allowing you to reach anyone in your phonebook. And its simple interface fades away when you’re in a call, so it’s just the two of you.
It uses the same technology — as well as hand-tuned and optimized codecs, bandwidth probing and other quality measures — to ensure that not only is your video available instantly (before you even answer the call), but also to ensure that call quality degrades gracefully as your connection fades. With dozens of proactive monitoring methods, your call quality will constantly improve and degrade on a bad connection, or remain crystal clear on a good one.
Duo is lightning-quick, encrypted and works on both iOS and Android. The team worked with WebRTC to create a new protocol that allows for instant creation of an encrypted connection, a feature that keeps you from answering the call only to be faced with a blank screen while you wait on both ends’ video feeds to catch up.
One of the coolest features is actually one of its biggest tech challenges — instant video.
By seeing the person on the other end, you have the power to answer the call — or not — while having information you wouldn’t have with a traditional video call or a standard phone call. This powerful feature could just change the way we make calls, which could lead to making a few more of them.
> A feature called Knock Knock shows you a live video preview of the caller before you pick up. Google says Duo calls are transmitted in up to 720p quality, with the app adjusting video quality on the fly so that it works well even on spotty networks.
All video calls via Duo are end-to-end encrypted by default and they seamlessly transition between cellular and Wi-Fi.
