What I'd like is an easy way to keep my notes synced on my laptop and my android phone. I suppose I could install git on my phone and do it that way, but maybe there's a less faffy way I'm missing?
I had previously been hosting TiddlyWiki from my phone, but offline editing + opportunistic syncing when on WiFi seems to fit a personal wiki better for me.
I'll admit it's not as UXy as pressing a sync button
Overall this setup Just Works for me.
Syncthing may be even easier, but I didn't try it since I am not sure if I can restrict it to LAN only.
Edit: It looks like it's backed by git so maybe it could be used for free, with a bit of faffing. Unfortunately I'm cheap and lazy.
Of course, you may experience some conflicts, but that's why you can pay them not to worry about that. Totally worth the price for me, though I do have a permanent discount ($5/month, as does everyone that signed up before Sep 30th).
