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.
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
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.
I don’t disagree, but taking notes in Signal gets you syncing automatically which is convenient and something OP asked for 🤷
