On iPhone, I recommend Monal.

Monal comes close.

To be honest, I think the above clients and services like Snikket fit that description.

Now, I wouldn’t say they’re all on the same level UX-wise as WhatsApp, Telegram etc. But I do think they are 90%-95% of the way there, and in my experience that’s enough to convince friends and family to switch over.

In my experience, when people haven’t wanted to switch, it’s normally not been because of the clients, but because they don’t want to install yet another app to talk to someone.

Any new open source software is always a net positive.

But, there are a few small caveats to the way they’ve done it (depending on how cynical/cautious you are):

• Because Proton are not accepting contributions, they own all the copyright, so can make the code closed source again if they want to (that wouldn’t affect the already released versions, but future versions)
• They could likely take down any derivative on iOS, since Apple will always take instruction from the copyright holder, for GPL’d code
• Since the builds are not reproducible, there’s no guarantee that the binaries they distribute are built from the source code

How do you define modern? I would call these modern clients personally:

• Android: Conversations
• iOS / MacOS: Monal
• Linux: Dino
• Windows: Gajim

It’s not perfect yet, but it’s much, much better than the old days.

OMEMO is supported by every major client, and they interoperate successfully. Unfortunately, most clients are stuck with an older version of the OMEMO spec. It’s not ideal, but it doesn’t cause any practical issue, unless you use Kaidan or UWPX, which only support the latest version.

All popular clients and servers support retrieving chat history now too.

In practice, I’ve been using it for several months to chat with friends and family, and haven’t had any issues.

Thanks for explaining some of the history, it makes some sense and gives me some things to try. Thanks for all the work you’ve done on the mobile stack as well. It’s made my life a lot better. And maybe one day I’ll be able to ditch the backup nokia too :)

I have a PinePhone Pro, and it runs nheko very well. Fractal is a little slower, but still usable. Not sure about Simplex I’m afraid.

I’m running postmarketOS v24.06. I could easily have messed something up though!

At least in my case! I ordered this year. It took 2 months, but it did arrive :)

If you can afford it, I think the Librem 5 is the best linux-first phone at the moment. Both it and the PinePhone Pro are roughly as fast as each other, but the Librem 5 has a much more premium feel, and the hardware kill switches are much more accessible, if you’re into that kind of thing.

Back in the day, when the Librem 5 was $1000+, it was a no-brainer for the PinePhone Pro, but I feel it is much more reasonable to recommend the Librem 5 now.

You can make it work as a daily driver, but I wouldn’t want to depend on it for life and death situations. Calling generally doesn’t work very well - either one side can’t hear the other, or the audio quality is too quiet, or not very good. It’s probably possible to fix if you know what you’re doing, but I don’t know what I’m doing :)

I carry around a dumbphone and a SIM removal tool, so that I can call someone if I really need to. If you’re happy to do that, I feel it gives you the best of both worlds.

Otherwise, one alternative is to be an Android-first device, that has good support in PostmarketOS, e.g. the Oneplus 6/6T. Mobile Linux has had such an impact on these devices that the price of these on eBay has gone up in some areas over time :D

Good luck!

I’d like to second Snikket - it’s designed for this use case and is very simple to set up.

If you’d rather not use Snikket, check out these recommendations for clients and servers.

Hope it works for you! Feel free to reach out if you have any questions.

Different strokes for different folks! I’ve been fortunate enough that many of my family and friends have been happy enough to follow me.

But I don’t disagree with you, Signal has a much more recognisable brand and better user experience. These are things that we need to improve if we’re going to get anywhere near the level of adoption Signal has.

How I Got a Truly Anonymous XMPP Account:

• Open my client (e.g. Conversations, Monal, Dino)
• Pick a random server, username and password
• Click register

Sorry, it’s a cheap joke, but it still baffles me that Signal requires a phone number, so I felt I had to post it :)

Of course, this is not XMPP-specific either, just my protocol of choice, there are many other open alternatives that also offer such functionality.

I originally suggested Monal to my friend (who is quite into iOS and really appreciates a well designed application) and she found the same, but then she tried Siskin, and was happy enough to use it to this day.

Just for reference, here are my favourites on each platform.

Each support modern XMPP extensions, interoperate very nicely with each other, and (at least in my opinion) look good!

• Android: Conversations
• iOS: Siskin
• Windows & Linux: Dino
• Mac OS: Beagle IM
• Web: Converse JS

As a note of caution, I used Oracle’s free tier to run a personal Matrix server, and it got deleted without any advance warning after a few months. I migrated to another provider and haven’t had any issues for 2+ years now.

I’ve had good fortune converting some family and friends to use XMPP.

People always mention fragmentation, and while there is some truth to it, it can be massively minimised by choosing blessed clients and servers for them to use.

In my case, I run my own server, and thoroughly test the clients (especially the onboarding flow) that I expect them to use, so that any question they have, I can help them out with quickly. Since we’re all on identically configured servers, it minimises one whole class of incompatibilities.

There is still unfortunately a bit of a usability gap compared to Signal - particularly on the iOS clients. But they have come a long way and are consistently improving.

Thank you! This is going to send me down a rabbit hole. I had no idea these phone cooling fans were a thing!
