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 Mexico City before you call. A “thinking of you” tap lights up their widget, and a countdown keeps the next visit in view.

Does daylight saving time change the call times?
Yes. In 2027 Houston changes its clocks on 14 March and 7 November and Mexico City does not change its clocks, so a call you keep at the same time in Houston moves by an hour in Mexico City on those dates. Check the table on this page and agree the new time out loud after each change.
