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 Baikal, but it seems Nextcloud is a popular solution.
Baikal is lean and great. I use it and sync to my Thunderbird (using the TbSync extension) and Android phone (using DAVx⁵).
