I’ve tried both, Obsidian Git and Termux (I need to try the last one without the git plugin in my mobile vault) but no matter what I always got merging problems (That I don’t know how to fix). Does anyone know how to fix this? Does Termux support merging?
Syncthing
It’s a FOSS, real time, continuous file sync
From personal experience, it works flawlessly between Linux and Android. And it supports Linux, Windows, MacOS, iOS, and Android.
Pairing two devices is seamless, although setting up folder sync can be a bit of a pain
Tip:
If you already have two copies of a folder on separate devices (A and B), you only need to add one copy into syncthing (device A). Then you can share it to the other devices (B), and map it to an [existing or new] folder on B
If you add the folder to A and B separately, then try to share it, you get duplicate “Share” folders, and it gets a bit confusing
The “Folder ID” should be the same across devices
