Setting reminders for yourself on your iPhone has never been easier. With iOS 9, Siri has received a major intelligence boost and is capable of understanding terms such as "it" or "this," which means you can now ask Siri to set a contextual reminder based on what you are looking at on your iPhone screen.
For example, If a friend invites you to dinner via text message and you want to make sure you don't forget to reply when you get home from work, while viewing the message, ask Siri to "create a reminder for this."
Siri will confirm this reminder with you and automatically add it to your Reminders list.
Siri can also remind you about things you're looking at in Safari, Mail, and Notes.
