what messaging app do you use?

So here's the thing, every time I try to move away from Facebook messenger I run into the same problem, nobody else in my friends or family actually want to use a secure, private messenger app like signal or telegram, my wife, my parents, my in-laws, my friends they're ALL on Facebook and they will never take signal seriously enough to actually use it, it really bums me out that there are these far superior options but without anyone else using them they're pointless..

Anyway what apps do you use to stay in touch with people?
