For me, this is the best calendar. Flexible visual customization and privacy. The only significant feature missing is the ability to sync via the Syncthing app. All that's needed is a separate shared directory for calendar events that can be synced. Then someone could implement a desktop app.

Basic calendar app that works with your phone's local calendars. You can schedule events, set reminders, view monthly, weekly, daily, etc., handle multiple event types, all the usual things you want to use a calendar for on your phone.

No ads, no tracking. Since it works on local calendars, you can use another app like DAVx5 to sync with an online service of your choice.
