Building a widget in Air Widgets does not place it — iOS does that part.
- Touch and hold an empty area of your Home Screen until the icons jiggle.
- Tap + in the corner and search for Air Widgets.
- Choose a size and add it.
- Touch and hold the new widget, tap Edit Widget, and choose the one you built.
That last step is the one people miss. A freshly placed widget does not know which of your widgets it should be until you pick it.
