SimpleX Chat is superior in anonymity and plausible deniability. It suffers a bit in UX compared to Signal though. Worthy tradeoff for most communications I'd argue.
Discussion
I have used SimpleX a lot. I haven't tried voice with it.
Oh yeah nice glad to hear you're all about it. Voice calls are decent, but uses WebRTC so it can be inconsistent depending on your browser settings. Signal works much more consistently for VoIP. Hopefully in the future SimpleX improves their call feature.
I never make phone calls anymore besides the wife really so that is why having a phone number just to chat on signal or whatever is lame.
Indeed it is.
