Due to the lack of calendar sets and a proper portrait mode week view on iOS of Fantastical v2 (and now v3, if you do not subscribe), I’ve been a user of Calendar 366 II for a long time.
On iOS I use a few Shortcurts that open various calendar sets in different views in Calendar 366 II. I’ve place those Shortcuts as icons on my Home Screen and put them in a folder together with the Calendar 366 II app icon, which shows the badge of todays appointments. The badge is conveniently carried over to the folder.
To enter new appointments quickly I rely on a series of Shortcuts with preset appointment details. For example I have one for gym and other sport planning, which I usually run on Sunday once. It presents me with a Shortcuts menu, with calculated dates for the next week. Due to the “allow select multiple entires” option for the menu action I can select all the days on which I plan to exercise. It will put the appointments either at the appropriate times, where my training locations are open or at 8am. Usually I run this task, when I’m at my Mac and where I can easily drag the appointment blocks around. It’s heavily tailored to my needs and will even include the estimated length of my various training blocks.
All those “add appointment” Shortcuts are placed together with a quick add Shortcuts that makes use of Fantastical’s natural language input in another Home Screen folder along with the Fantastical app icon showing the current calendar week as a badge count.
I practically don’t open the Fantastical app on iOS, because the DayTicker view is of no use to me and physically rotating the phone to get a week view is too cumbersome. Calendar 366 II offers me the views I need with ease.
If Fantastical would offer me an option to unlock the features “calendar sets” and the “portrait mode day/week/month views” with a one time in-app purchase, I would consider using Fantastical only, because it is well programmed. The issues I have is solely business model based. The subscription price is too high for those two features.
On macOS I use Calendar 366 II as a menubar app to have a way to quickly peek at my schedule, along with the Fantastical menubar icon (showing the calendar week number). Hyperkey + C will expand Calendar 366 II, Hyperkey + F will open the add appointment dialog of Fantastical’s menubar utility.
If I need to do serious calendar planning I’ll open Fantastical on the Mac, where I can easily toggle calendar sets.
I also use the Fantastical Alfred workflow sometimes to quickly add an appointment, but I prefer the visual reprsentation of Fantastical’s menubar app, because it allows me to tweak notifications and duration with ease in the GUI.
On the Watch I use Fantastical’s complication for the Infograph Modular large middle complication, because I like the very visual time block representation of my schedule, and Calendar 366 II for the Infograph’s top sub-dial circular complication so that the next appointment’s title is shown across the dial.
Why both? Tapping the Calendar 366 II complication will present you with a month view just a swipe to the left. Fantastical offers the v2 legacy natural language input on the Watch.
