Apple's much-anticipated new operating system, iOS 8, was released to the public on Sept. 17.

Among the changes is something called widgets in the Notification Center. Widgets give you information at a glance, right from the Notification Center screen. Some widgets even allow you to interact with the app, without having to actually go to the app and open it.

To see which apps you own that already take advantage of Notification Center widgets, go to the "today" section of Notification Center and scroll down. Tap on "Edit," and you'll see a list of apps that you can see from the Notification Center.

Widgets in Notification Center make it easier to interact with apps, without having to launch the app itself.

Some apps that take advantage of widgets come preloaded on your phone, such as the Stocks app and the Reminders app.

There are a bunch of apps that take advantage of widgets, and the list will just keep growing.
