NarendraCzarits even more outdated
7777AKASignal is the best.
The thing it’s missing the most is better multi device support and an updated desktop client.
For me, I think Matrix is more complete (specially since it backs-up your chats and media encrypted). The only thing it’s lacking (at least Element specific) is encrypted chat search support on mobile.
There’s no way that we can have a mainstream alternative to imessage if we keep declaring a new app or protocol the new best one every two years.
iMessage can’t be “the mainstream” app by locking out most of the world tho. Plus it is definitely the ugliest thing Apple has ever made in its lifetime that I know of.
