I tried SimpleX but the VPN kill switch on my phone prevents syncing with my computer.
I use telegram primarily as a note taking app with sync features.
Occasionally I send files to friends, so having easy set up for tech illiterate would be great.
And the post is about telegram alternative?
Try Nostr, I dunno. Or VKontakte if you want the Telegram functionality of sending transcripts of your communications to FSB.
