And here is where Google Hangouts comes in. Google Duo offers video and voice calling, but it misses the important chat function. Unlike Google Allo, Google Hangouts has a capable web version, it’s perfectly integrated with Gmail service, and the feature list is good enough to keep the users in the loop. The focus switched back to Google Hangouts again. Unfortunately, Google Allo never gained traction among the users, and the search giant scrapped the project in 2018. The company quietly shifted the Hangout branding to the enterprise users and retained Allo and Duo for the consumers. In 2016, Google announced Google Allo and Duo apps for Android and iOS users.
