I was looking for a way to sync files betwteen devices. I tried the bloated Dropbox, but my files are on someone else's server. So I tried Syncthing. It was easy configure, and today I put it to a real world test. While it's not strictly syncing to Zettlr, Syncthing is installed on my phone and Debian PC at home, keeping my markdown files synced.
Today I sat in a lab waiting waiting room for over 2 hours to get a blood test. That would normally have been dead time for me, but today was different.
I worked on my files in the Markdown app, a minimal md editor I found on the Playstore. I got so much work done and returned home to everything being up to date ready for me to continue working in Zettlr. It's now part of my daily workflow. I'm sure I can do better than Markdown for the Android, so what other combinations do you use and trust?
