There are some demographics where its usage is extremely common. I’ve come across multiple people who are on FaceTime calls while in public. Just walking around on video and speaker, talking to someone else. I can’t conceive of using it this way, but in some social circles it’s totally normalized.

This page has some interesting quotes. Reading through, it sounds like it’s hovering at or below the top 5 most common video chat tools. There’s a lot of bias towards quotes about 2020 usage so that’s obviously skewed, but that year at least 9-25% of various demographics were cited using FaceTime daily.

I use FaceTime 2-3 times a year to talk to my nephew, and maybe 3-5 times a year to screen share or show my mum things. But I do use Teams video calls literally 5 days a week (I try to avoid the video part when I can, but there are a few in leadership who really push for it. My company is never doing RTO, so I’ll accept a bit of video calling for the sake of permanent WFH!).
