I'm surprised Google Duo hasn't become more popular. It's a great cross-platform video chat app. I especially like the feature where you can see the other party before you answer their call. I have taken calls because of that feature that I otherwise wouldn't have.
It's better than FaceTime because it works on Android. It's better than Skype and Google Hangouts because your cellphone number is your identity; you don't have to log in with any usernames or passwords. Extremely low friction.
