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.
Signal needs a phone number
“Don’t you guys have phones?”
Also, I htought 99% of tablets connect to the mobile network using a SIMcard, but even if you rely only on wifi, see my previous quote.
which does not need to be in the tablet
It does. The Signal app for Android does not support being a secondary device. It must be the primary device with a phone number.
In addition, whatever Play Store settings they use excluded all of our tablets, even the one that had a SIM. Manually installing the APK worked for this case, but that didn’t really solve our problem.
