I like the signal mobile app better, but wire has a proper desktop client along with video calls, so wire is what I ended up with. Of course that's only with those close friends I can convince to join me on wire.

I did read that facebook messenger now has end to end encryption, but as far as I can tell this is only for "secret" conversations - which are only available from the device you initiate the conversation from. Whatsapp would probably be a good choice if you (OP) have a lot of friends already using it.

Wire was in the middle of a shitstorm a while back iirc because it falsly advertised that it encrypted everything end-to-end, when in actual fact only text was so.
