iTunes in the Cloud lets you access the content you've purchased from iTunes Store, the App Store, and iBooks Store from any device you have linked to your iTunes account. This lets you re-download previous purchases on your iPhone or iPad, as well as Macs or Windows PCs through iTunes. All of your content is also available on the Apple TV, making it easy to access no matter what screen you're using.

The iTunes and App Stores are often central components in our digital lives, offering an ever-expanding catalog of music, movies, apps, games, and more for us to peruse and download.

Automatic download is an excellent, helpful feature of iOS, making it easy to download your purchases across multiple devices. Once you've enabled automatic downloads, anything you download or purchase on one device, including apps, books, movies, and music, will be available on your other devices as well.

The Apple TV not only lets you use services like Netflix, Hulu, and many other live and on-demand video service, but it also lets you access all your iTunes in the Cloud content for streaming.

App Store

Many of us have a single Apple ID that we use for all of our purchases. However, that isn't always the case. Perhaps you have purchases between two accounts or you've decided to merge accounts. Regardless of the reason, you can quickly sign out of one iTunes account and into another one using the Settings app on any iPhone and iPad. Just remember that due to licensing and regulatory restrictions, Apple only lets you switch between Apple IDs every 90 days in most countries.

Maybe it's time to get rid of an older device by passing it down or trading it in. Maybe you've just had your device stolen, and need to protect your accounts. In any case, you'll want to de-authorize it from being able to access your iTunes account. This prevents future purchases on that device from being made using your iTunes account and payment information. If you ever use that device again, it's easy to restore access by simply signing in to iTunes.
