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.
Honestly? For that limited use, there’s really no need to switch.
However, if you’re willing to do a little extra effort, Join, by joao apps can do what you’re wanting. The notes is easy as pie. Sending files to your own devices is easy. Then you just need a different file sharing method for others.
It’s not a 1:1 replacement, obviously, but sending files via email, or other methods, when it’s only occasional isn’t something that needs to be part of a messenger service that you aren’t primarily using for messages in the first place. Keeping all your eggs in one basket isn’t always as good.
