After showing us Allo and Duo in March it's finally time for Google's new videocalling app Duo to come out for iOS and Android.
This apps was criticized for doing the same sort of thing you can already do in Hangouts, but Google hopes its simplicity and speed will win you over - and besides, for this app you need no Google account, you just need a phone number (like Viber and other apps).
Although it uses WebRTC, Google takes great pride in all the optimizations it did, in order for Duo to work "flawlessly" regradless of network conditions. It can adjust its quality in real time, and can even deal with mobile to WiFi networks transitions (and vice-versa) during a call. But its key point is the Knock Knock feature.
If you have it enabled, you'll be able to see who's calling you even before you pick up, just like you would be able to check out who's knocking at your door before you open it. It's a really nice feature that makes us wish all other apps did the same, but the fact remains... will it be enough for you to keep using it after the initial novelty phase? Or will you simply revert back to using Hangouts or WhatsApp or Snapchat, or whatever most your friends are using?
