One of my favourite improvements that I've used in iOS 10 is the new widget (or Today) view. Swiping to the left of the homescreen there is a new view that shows date along with your selected widgets, here are some of my favourites
- Up Next (I use Reminders now, this widget uses the Calendar and Reminders to show what you have up next on your schedule)
- Maps Destinations (shows parked car and travel time for any upcoming appointments)
What are your favourites?
