Stop doing the math every day
The Long Goodbye keeps your person’s local time and time of day on your home-screen widget and lock screen, so you can see whether it is morning coffee or midnight in Calgary before you call. A “thinking of you” tap lights up their widget, and a countdown keeps the next visit in view.
