There’s also a companion messaging app, called Allo, coming soon.Until then, this is your first glimpse into Google’s attempt at revamping its messaging suite. It’s way too soon to tell, especially since Duo feels like it’s still under construction. Duo allows you sign up with just your phone number.And if you’re calling someone, Duo will let you know that everything you’re doing can be seen by the recipient, so don’t try to pick your nose before they pick up!If you're on Android, you can see the caller even on the lock screen.It really feels like it was designed for a single mobile phone at a time. Duo is cross-platform, but it’s only available for i OS and Android since they’re the two most used mobile operating systems.It's also not available for Windows, OS X, or Chrome OS..
Google will release a messaging app called Allo for text and images and the like—why they're separate apps instead of integrated, we can't figure out. The app will drop video and go to audio if network conditions are really bad, but there's simply no "make an audio call" button for some reason.But it might actually address one of the bigger shortcomings with text messaging.Yahoo thinks it can fix video chat with a simple formula: Take a text-messaging conversation and overlay it atop a live video feed of the two people having the conversation but mute the audio.But if you’re curious about what Google is gunning for, here’s what to know. Once you install it, you’ll receive a verification code via SMS to ensure that it’s actually you that’s signing in.You can theoretically sign in from any phone using that phone number as long as you have also the phone it’s connected to near you to receive the verification code.But it's not optimized for i Pad; it runs in "blown-up i Phone app" mode.
