Tap it, and your day unrolls like a page from a notebook — ruled lines, handwritten font, and all. WRITE OR SPEAK YOUR TASKS Type naturally — "gym tomorrow 7am every weekday" — and dates, times, and repeats are detected automatically. Or just tap the mic and say it out loud. ROUTINES THAT ACTUALLY REPEAT Mark a task as part of a routine, give it a name like "Morning Routine," and it repeats daily automatically — grouped together the next time you check your list.
