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 !syncthing@programming.dev. Does anyone have any leads?
Hmm, I just now learned about Fruux, in this Reddit post…


Isn’t calendar syncing a solved problem? If you set up your own CalDAV server you can pretty much use most any mainstream calendar app you want without having to rely on 3rd party services. Or maybe I’m misunderstanding your request?
I’ve heard of this, but I can’t self-host as I lack reliable Internet access at home and don’t want to run a machine 24/7, or am I misunderstanding how CalDAV works? Can it operate solely via Syncthing, in one way or another?
To clarify, I don’t pay for an ISP-provided Internet subscription at all (some people were really picky on here about this wording and me not just saying, “I don’t have Wi-Fi at home”); it’s way cheaper for me (saving >$600/year) to just carry a hotspot device with me at all times.
Many e-mail providers such as mailbox also provide calendar synchronization via CalDAV.
You could use a free VM on Oracle cloud infrastructure and create regular backups in case thwy rugpull the VM (as it’s free)
