Much better (and cheaper) than Fantastical

I deleted Fantastical after a trial because I felt the interface was too cluttered. And so, I continued my quest for the perfect app that combined calendar events and reminders in a single view. I tried everything and none were satisfying: The ones I sort of liked would not syc with iOS reminders and calendar, so that was a no-no, and others that did were too heavily calendar or reminders oriented. This app strikes just the right balance. It barely occupies space (it sits on the menu bar), you can open it quickly for a clean overview of upcoming commitments and you can quickly add events and reminders. I still like my iOS calendar and reminders notifications bette: For iOS calendars, notifications don't tell you how long ago you were notified but how long you have till your event, and iOS reminders notifications persist on your notifications screen until you deal with them. This is a limitation of not just Calendar 366, but of any other non-stock app. However, I simply add events and reminders on Calendar 366 and, since it syncs with iOS calendars and reminders app, I simply set it up so that I only get notifications through the stock apps. Just my two cents about how you can make the most out of this app. Maybe a few more theme customizations would not hurt, but other than that, BIG THUMBS UP!!!

Calendar App

I have used Calendar 366 II for so long that it's just a part of my life now. I didn't really realize it until I moved to Big Sur and Big Sur added another clock to my menu bar which drives me crazy because it's messing with my Calendar 366! I really can't live without it anymore. It handles multiple calendars better than any other app and I can quickly get into my online meetings when I'm running late by 3 clicks: One to open Calendar 366, one to click on the event in question (because today's events are already showing for me) and one to click from the event discription to open the meeting. Wonderful.

Great, but something has changed...

I've been usingthis app since it came out. I 've always thought it was the perfect calendar app. Now I don't know if this feature changed in a recent update or I'm just missing something. You used to be able to SET REMINDERS for an hour, 2 hours, 15 mins before an event, now you can only set it to a specific time on that date. If the developer sees this, can you please let me knon if I'm missing something or add that feature back.
