Additionally, FaceTime automatically registers your phone number, so once you set up your iPhone, you’re also good to go on FaceTime and can start making audio and video calls right away.īoth apps have similar features, but there are some that set each one apart. SetupĪs mentioned above, FaceTime is installed by default on all iOS devices and most Mac OS computers, so you don’t need to manually perform an installation on your iPhone. FaceTime is installed by default on all iOS devices and also comes with Macs on OS X or later, which means you have access to every iOS and Mac user by default from FaceTime. There is a caveat here however: Google Duo shows only contacts in your phonebook that also have Google Duo installed and does not allow you manually input phone numbers or email addresses like Skype, effectively making it possible to only contact those who are also using Google Duo. Hence, Google Duo grants you access to a wider range of contacts, allowing you to keep all your communications in one place regardless of the device you’re using.

Google Duo, on the other hand, is available on Android, iPhone, and iPad, and can be used on the web on any platform with access to an internet browser. As noted earlier, FaceTime is available only on Apple’s platforms (that includes iOS, watchOS, and macOS), which means there’s no way to make contact with people no other platforms from FaceTime.
