We first learned about Google Duo gaining audio-only calling capabilities last month, and now Justin Uberti on Twitter has confirmed that the feature currently rolling out worldwide to both Android and iOS users. The feature can be used by flicking a toggle at the top of the app. You’ll then be able to use a Wi-Fi or cellular connection to place a free audio call to another Duo user. It might be hard to find one, mind you, but they’re out there.
