Handoff
Handoff enables you to seamlessly move from one device to another and carry on working in the same app in an instant. If you are working on a document on your Mac – in Pages, for example – and you pick up your iPhone or iPad, you’ll see that app’s icon at the bottom-left corner of the Lock screen. Swipe upwards from it to be taken to the same app and document on your iPhone, ready for you to continue working.
