Is there anything better than SimpleX for total anonimity?
Although I also use Molly, a modified version of Signal, even with people that have my number for Signal I still prefer SimpleX for everybody, but unfortunately Molly/Signal is easier for some people.
Especially for things like resetting phone or changing phones, with Molly they know where I am and there’s no need for an invite link with SimpleX, but I still grealy prefer it.
I’ve looked at Delta chat and have wondered if it’s worth it. I only use webmail on computer for all of my emails because I need the screen real estate, zero email on phone. Phone is only calling and messaging.
Should I give Delta chat a try for doing long form emails including documents?
Only if you like the “Messenger App” form factor. Delta chat is nothing but a mail client with a messenger UI. Fortunately, that includes automatic PGP encryption for users who do not know what that is (similar to what whatsapp/signal did for E2EE).
You can still try it out. It literally has no downsides. And if you like to use it as a chat-client only, it supports that option, too.
