You can view information from your favorite apps without opening them by using widgets on your iPhone. Widgets can be used on the home screen, lock screen, or by swiping right to access Today View from the home screen or lock screen.
For widgets to appear on your home screen:
Touch and hold a widget or an empty space on the Home Screen until the apps jiggle.
In the upper left corner, press the Add button.
Tap Add Widget after selecting a widget and a widget size.
Click Done.
Widgets from the Today View may be added:
In Today View, press and hold a widget or an empty space until the apps wiggle. From the home screen or lock screen, swipe right to get Today View.
In the upper left corner, click the add button.
To select a widget, scroll down and select one of three sizes.
Once you’ve added a widget, press Done.
