Google Hangouts. Google Hangouts is a communication platform developed by Google which includes instant messaging, video chat, SMS and VOIP features. It replaces three messaging products that Google had implemented concurrently within its services, including Google Talk, Google+ Messenger (formerly: Huddle), and Hangouts, a video chat system present within Google+.
Duo is available now in the App Store and Google Play Store. Why this matters: Hangouts has long been a mess, offering a buggy and inconsistent experience for video calling and messaging. Duo is the first of Googleâs new, well, duo of apps designed to remedy this. Allo is an iMessage-style app that should also launch soon, promising to bring you cross-platform messaging bliss with the smarts of the new Google Assistant.
