You didn’t write it down.
Your day did.
What a Day turns your places, photos, weather, sleep, workouts and calendar into one timeline — then writes a one-line summary of your day. You just live it.
iPhone · iPad · Apple Watch · iOS 27 or later


THESE SHOW UP ON YOUR TIMELINE BY THEMSELVES
When and where, on a single line
The list answers “what did I do, and when.” The map answers “where.” Same records, same selection — switch views and nothing gets lost.
- The whole day’s weather as one card — and rain becomes an event
- Split sleep on one dial, with deep and REM at a glance
- Driving, walking or cycling, detected for you — with the songs you played



One line a day, written for you
Your daily summary is drafted from the day’s facts. Edit it directly, or ask AI to rewrite it in another direction. Don’t like it? Undo.
Runs on-device with Apple Intelligence — nothing goes to a server
Look back on a week, a month, a year
Distance, bedtimes, weather and moods, by week, month and year — or flip to a cover calendar, one photo per day.
