I just use the calendar complication (I use Infograph and i put calendar as the top inner complication) to keep me up to date on everything and have the reminder widget in the smart stack. I use Siri to quickly add stuff to calendar and reminders since I’m typically a disorganized person. Its really helped me since ill be reminded of my events everytime i look at my wrist. Other than that, my watch face is focused on fitness like water intake tracking and my rings, and other complications are shortcuts to music apps.
