Not Threema, anyways: they talk a big security and privacy game but they're closed source, which is incompatible with privacy.
I tried Wire years ago and had issues with calls when I was behind a NAT connection, but I hear people raving about it these days so surely it's fixed? Signal I've used with my family with little issue: less feature-rich but the features work. When things break on non-Google/Facebook/Apple stuff, people are more critical and quit faster..
@cathal Yeah, the closed source part is irritating. But then again they also have a business model I understand, so there’s at least that going for them.
