Since quite some years I use CalDAV-Sync to sync my Owncloud calendar data to my Android phone (Pixel 3, stock Android, in case that matters).
Now, I’m migrating to Nextcloud and read in the documentation that DAVx$^5$ is recommended as the Android sync tool. Checking the Google Play Store, I see that CalDAV-Sync hasn’t had updates for years (Android warns me that it was made for an old version), while DAVx seems to be in active development. Nevertheless, CalDAV-sync worked with few glitches for many years.
Can anybody in this forum give advice if a migration from CalDAV-Sync to DAVx[**] is sensible? (I searched the forum, but didn’t find any topic that discuss these sync apps.) I’m reluctant to throw away a working solution[*], but I’m willing to explore a new better solution that’s actively developped.
[*] IMHO, that some app isn’t updated doesn’t imply that it doesn’t work any more. It might simply be finished – I’m from the TeX community, using a »finished« program from 1982… ;-/ OTOH, that my Android phone warns me about that app should warrant an update from the developers, so this might really be a discarded app.
[**] People should use project names that one can enter on a standard keyboard. Sigh, I’m getting old.
