I’m looking for this too and am interested in any answers. The stock GrapheneOS messaging app is okay for just text messaging for me, but I’d also like to be able to have an interface to it on my PC, either in the web browser or as a separate app. Google Messages for Web is really the only thing I miss from enshittified Google Android. I wish Signal didn’t remove their capabilities for making Signal the default SMS app on phones, but they likely had good reasons to do so.
I’ll share this post on the Fediverse; maybe we’ll get more traffic and thus more answers that way. To be honest, though, I’m not expecting anything that satisfies.
This looks promising as a stock GrapheneOS message app replacement. One of the things that kinda irks me about the stock app is that reactions are displayed as text and the user doesn’t have the ability to react to messages. With Textra both are possible. Thanks for the suggestion!
