Very good Nostr client to substitute whatsapp, telegram, signal...

Hmm, how is it compared to simplex?
They are different, SimpleX it’s more complete, but it isn’t build on Nostr, let’s see what will happen, this is a start 👍🏼
Fizeram um bom trabalho no design
There is a metadata leak in Nostr DMs so the same problem could be present in the app 0xchat. I would use Session, SimpleX or XMPP instead of 0xChat.
There are other interesting choices like Briar or Cwtch.
It’s true, if you want to be private you need to use your own relay, only shared with those who you trust.
