I would use simplex if there was a desktop client. I like Signal because I can use it across all my devices.

Another super cool thing about it is that it's written entirely in Haskell!
I did a bit of research for my personal use and what came out as the best options in 2023 are indeed SimpleX and Briar. What do you think of the latter?
The last time I tried Briar felt more of an emergency scenario pick then a comfortable one, it can do videocalls right now? Valid project btw.
Seems that's true. Text-only communication in Briar is built by design. I see this from its communication scheme. I don't think any other message options will come up. So I am also on it in case of the Internet outage. Besides, you can chat properly only when you and your contact are both online. Not a very handy option for daily use.
So SimpleX.Chat for privacy and Matrix for public groups.
Looks like they have 'public groups' in their roadmap: https://github.com/simplex-chat/simplex-chat#roadmap
Briar is secure and private and works reliable. However it eats a lot of battery and no audio or video.
Im not a fan of no identifiers. Sure simplex is secure with it but I would like to see something like simplex that uses 24 word seed phrases to generste millions of unique identifiers the user can easily backup and restore from a piece of paper and not from a digital backup file.
Monero is a privacy coin that allows for multiple subaddresses.
The reason I prefer having identities (subaddresses) and to recover these addresses using a single 24 word seed phrase is for a simple one-time backup of your addresses. This will not backup anything else.
Lets say you generate a subaddress for every single friend you have and then a few years later your phone dies and you did not make a backup in over a year. The seed phrase will be able to recover your subaddresses. You may not know who address is for which friend, but as long your friend knows they can contact you and you will still receive the message.
If simplex implements multiple reuseable addresses that are generated by a seed phrase like a cryptocurrency, it will be a killer app. I am not against removing the single use one time codes to establish communications, that is a cool feature, just not possible to backup these communications on paper.
Paper backups are considered the most secure since it is not backup using a computer.
I have not
Instead of simply criticizing SimpleX, talk with the developers directly about a passphrase recovery and see what they have to say about it for them to address your point directly insteadig of you saying it but never sharing your feedback with them.
I am not complaining about SimpleX. Just expressing a feature I would like to see. I could try to reach out to the devs about it though.
Personally it's between SimpleX and Briar, but SimpleX having an iPhone app so people I know can use it makes it win out.
Simplex chat isn't really decentralized. This makes it simpler at the cost of centralization
It's not P2P, but it definitely is decentralized, as in anyone can set up a server:

Anyone can set up a server indeed, and you have no real way of knowing if you can trust them or not.
The official SimpleX chat website has this nice advice in this regard:
The servers have separate Anonymous credentials for each queue, and do not know which users they belong to. Users can further improve metadata privacy by using Tor to access servers, preventing corellation by IP address.
But IMHO if you need Tor to get the resemblence of metadata privacy, why use SimpleX at all and just use XMPP with Tor with works great?
To me this SimpleX is pure techno-solutionism that tries to solve a hypothetical problem and ends up as basically security LARPing and not solving many real-world threat-models at all.
I kinda get where you're coming from, but I think your perspective might be too "techy". I actually do use XMPP myself for the time being, but I have like half a dozen contacts on it. IMO because the set up process, presentation and apps fit a protocol born in early 2000s. Which might not bother some IT guys, but you'll lose all the normies. SimpleX is on a whole other level it that regard, but keeps the benefit of being as secure, if not more. I have high hopes this app could become the signal killer we need.
We are together with you in favor of XMPP (I am with both hands)! You just "won't sell" that kind of solution to very many people. We are already living in a zoo of messengers. We need to come up with at least two that will cover all the basic needs and offer sufficient privacy.
