Edit Reminders on your Apple Watch
The Reminders app in watchOS 9 is also getting a significant upgrade that will take it beyond just a place to view and check off your reminders.
With watchOS 9, you’ll be able to edit just about everything in a reminder that you can from your iPhone. This includes adjusting the date and time, flagging a reminder, changing its priority, adding notes and tags, setting location reminders, or even assigning it to a different list. For Apple Watch users, this alone makes Reminders a much more powerful task management app than ever before and puts it well ahead of the competition, most of which offer little to no editing capabilities.
