Widgets give you an easy way to view current information at a glance—today’s headlines, weather, reminders, battery levels, and more. You can view widgets in Today View and add them to your Home Screen or Lock Screen to keep this information at your fingertips.
You can interact with widgets on the Home Screen and Lock Screen without opening the app—you can take action on the widgets for Music, Podcasts, Safari, Home, Contacts, and more. For example, tap Move apps and widgets on the iPad Home Screen
