Can hook you up with an invite to cron or amie.so if you want

Can anyone recommend a good desktop app for keeping track of appointments/daily tasks? Some kind of calendar? I just need something because right now I’m using a paper calendar and that has to stop 😅

Cron does the job well. Here is a link to download cron.com/download/macos
I use Fantastical for calendar (available both on ios and osx) but for task management and productivity, Things has been the recent favorite: culturedcode.com/things/
I use Reminders. I have a “today” list, a “this week” list and a “someday” list. Works well for me.
