Google Duo was a proprietary voice over IP (VoIP) and videotelephony service released in 2016 by Google and merged into its Google Meet product in 2022. It was available for Android, IOS and web browsers. It let users make and receive one-to-one and group audio and video calls with other Duo users in high definition, using end-to-end encryption by default. Duo could be used either with a phone number or a Google account, allowing users to call someone from their contact list.
Google Duo was announced at Google's developer conference on May 18, 2016, and began its worldwide release on August 16, 2016. Google announced in 2022 that the service would be merged into Google Meet, and it was shut down by the end of the year.
