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?
edit / wait - an alternative for telegram as a note taking app??
There’s a note to self feature in Signal
there are decent note apps, like notally, that are smaller than 2mb 🤷
https://f-droid.org/packages/com.kin.easynotes/ 3mb
https://f-droid.org/packages/io.github.quillpad/ 4.6 and it can sync
https://f-droid.org/packages/org.fossify.notes/ 8.9
and than there’s joplin
I don’t disagree, but taking notes in Signal gets you syncing automatically which is convenient and something OP asked for 🤷
Standard Notes is my go to for notes 100%. It’s all about privacy through encryption and is FOSS. Plus for this specific scenario, it also allows for notes export.

Friends used telegram so I had the app installed. It was easier to store documents in telegram than in one drive or proton drive, so telegram became my go too. Obviously not the best setup, but it worked and was easy. I’ll try out Signal and Matrix, but continence is a big factor in my choice.
