Handoff and Suggested Apps on Your iPad
In the General settings, the Handoff feature, added to your iPad with iOS 8, lets you start a task (such as typing an email) on your iPad, on another iOS 8 device, or on a Mac computer running OS X Yosemite, and resume the task on another iPad, iOS 8 device, or Mac.
All the devices have to be running the identical iCloud account. On the tablet, you’ll be able to resume with the app from your lock screen or app switcher. On a Mac, you’ll see the appropriate app on the dock.
In the Suggested Apps section, you can flip on a setting to showcase installed apps or App Store suggestions relevant to your current location. Such suggestions appear on the lock screen and in the app switcher.
