Siri makes suggestions for what you might want to do next, such as confirm an appointment or send an email, based on your routines and how you use your apps.
For example, Siri might help when you do any of the following:
Glance at the Lock Screen or start a search: As Siri learns your routines, you get suggestions for just what you need, at just the right time.
Create email and events: When you start adding people to an email or calendar event, Siri suggests the people you included in previous emails or events.
Type: As you enter text, Siri can suggest names of movies, places—anything you viewed on iPad recently. If you tell a friend you’re on your way, Siri can even suggest your estimated arrival time.
Confirm an appointment or book a flight on a travel website: (iPad Air 2 and later) Siri asks if you want to add it to your calendar.
Siri Suggestions are on by default for your apps. You can turn them off or change the settings at any time.
