I see a lot of people are upset about the new subscription model. I do agree it's *way* overpriced (do the math: after 5 years you'll have paid $200!), but as a purchaser several years ago, the now-paid features I use (like multiple calendar sets and duplicate combining) haven't been taken away. Having said that, I don't use most of the premium features anyway (tasks, invites & scheduling, Hangouts/Zoom, templates), so do with that what you will.
Having said all that, Fantastical is still the best calendar app for Mac by leaps and bounds, with a much better UI and features nobody else has. The calendar sets are a huge improvement over every other app (with a keystroke, I can quickly switch between work calendars, private calendars, and calendars I share with family), the Menu Bar UI is great, v3 finally makes the full-screen view an actual app that you can reach via CMD+TAB.
Shortcomings: User cannot choose to show empty days in the scrolling view (I want to see my empty days!), all-day events with short names appear side-by-side instead of in a list (which makes events just look like a jumble), I'd prefer timed events to be in a colored bar just like all-day events instead of just having a colored dot (should be an option), and v3 changed the Menu Bar dropdown to be white on top, so the fields for entering new events and searching now blend in with the calendar instead of standing out like they should.
So, in short, leaps and bounds better than any competitor, but room for improvement, and yes, the new subscription pricing is way too much. Fantastical has always been pricy, but changing from $50 once to $40 *per year* is ridiculous, and this bad choice is going to hurt the app's market share and discourage new user uptake, which is a shame because Fantastical is fantastic.
