Android

Whatever the other person uses. Everyone uses something different and I raarely feel like convincing someone to switch to something new, much less helping them figure out how to do it. Of my circle of friends, it's least painful for me to just find out what they already use and install it myself.

I usually use Signal.

Signal

Signal.

Jitsi.

No installs required on any participant. No login required (except for host recently). No time limit or user limit (maybe there is but we use it and have never had any problems). Works awesome.

Google meet for most people and WhatsApp video with family.

Everyone I communicate with regularly uses Signal, so Signal when it's needed. But it's very rare.

For work, Jitsi. Also Whereby.

Jitsi's the easiest cause you can just pop it open and start using it without registration. And the rooms you use are deleted after some amount of days (can't remember exactly how many days).

Discord.

Zoom was the easiest, since you can send someone a link and the other person doesn't have to download anything, but I think plenty of other video conferencing apps have that feature now.

Whatever you used don't use Microsoft teams. I'm so so sick and tired of that piece of crap. Literally anything will fail, at random. Need to demo a software update to a coworker? Ups, screen share suddenly just gives a black display. Now your audio just flat out refuses to work. Now you don't have a camera. Half the calls I get won't ring on my Desktop, incant pick up the call. Teams mobile on Android is a similar shit show.

Then, Go to google Meet, everything works perfectly fine and the video quality is just plain better.

Yet so many companies have this "we need to do everything with Microsoft because Microsoft goooood"

Edit: just saw this is an Android sub. My bad. Still, I'll leave it here because teams on Android is a shit show as well, so is Microsoft skype.

I use WhatsApp with my immediate family, outside of which I just don't do video calls at all

Mostly Meet. My family is mostly on android and it comes pre installed and built into the phone app most of the time so it's really easy to get the older family members to use. I did have to have my Parents download it on their iPhones but they didn't fight cause video calling the grandchild is important lol.

I avoid video chat as much as possible, but use Jitsi at work.

Work: MS teams if it's internal or the client uses teams. Zoom typically if they don't. Slack for on demand calls.

Home: what's app video calls.

Meet, Discord, Signal. Depends on who I'm calling.

I was lucky to be able to convince most of my family to use Telegram. Now that they are comfortable I can't get them to try anything else.

I really like Telegram generally, including for voice and video. Having native desktop clients too sweetens the deal, even on platforms like Linux. Plus it feels fairly native on each platform, so that makes it easier to get people to switch, versus “this app feels too foreign/clunky on my OS”. Signal is a pretty lousy experience on iOS for example.

Teams at work, nothing at home because why would I want to talk to anyone other than my wife

Discord and Messenger yeah I know their awful but I have no other choice my whole family and friends dgaf about privacy and stuff like that

Discord. Thats what my friends use

Webex at Work (best endpoints) Portal for family WebRTC based server with STUN for friends

Before, I used to use Google Duo, now using whatsbapp video calls (quality is poor compared to snapchat video call).

Usually one of the big three for work: Zoom, Meets or Teams.

Personal it depends, but usually Telegram or Discord.

Of all the services I used so far, the one I hate most is Teams. It has the highest rate of issues and not always the easiest to troubleshoot.

Teams for work and when I ever need to for personal calls which is really rare, Telegram.

FaceTime

It’s such a rare use case that there’s no point in installing something else for me
