I’m late on this, but Jason Snell overviewing Fantastical’s new watch app and complication:
I’ve seen complaints today about Fantastical’s small complication, which simply displays how many more events you’ve got on a given day. (I’m not sure what else it would do in that space, frankly.)
Here’s the simple answer from me – the day’s date. I added the complication, only to delete it seconds later when I realized it showed events remaining and not the date.
