I’m looking for a google calendar replacement that isn’t nextcloud, has a descent mobile app with widgets, and authentication built in. I’ve seen plenty of recommendations via search but i’d like to hear what you personally use and what you like about it.
I use Nextcloud’s Calendar to sync to other calendar apps over CalDAV.
Same. Thunderbird now has native support for CalDAV and I use DAVx5 to sync it with my Android devices.
