Edit: I seek a server-less solution.
The only thing I can see is Linwood Flow but it looks like it’s a really, really long way off before becoming a primary calendar app.
If it could just store all calendar content in 1 local file, then that could be so easily auto-synced across devices with [email protected]. Does anyone have any leads?
Hmm, I just now learned about Fruux, in this Reddit post…


Ah, I see. No, that’s not the kind of use case I had envisioned. I don’t think my suggestion is relevant to your problem then, sorry. Maybe one of the many calendar applications has a portable version that can entirely live in a Syncthing directory…? But then that wouldn’t be platform-agnostic. Hm.
Syncthing is Win+Mac+Linux-compatible! That’s actually what I was going for, but didn’t think of looking for a portable version for some reason… Thanks for the idea!
Yeah, but the binary of the program won’t be platform-agnostic, that’s what I meant!
Oh, right, based on what (little) I’ve seen, yeah…
