Use this section when an iPhone needs to support a real daily task: calling family, opening a schedule, viewing photos or reaching a selected website. Start with the person and the route, then choose Assistive Access, Guided Access or Kiosk Web Launcher only when it solves the actual problem.
Design for recognition
Keep the important action visible, familiar and recoverable. A tidy screen is not enough if the person cannot tell what to do next.
Test the whole route
Check the normal path, a wrong turn, a permission prompt and the way back. The goal is more independent use, not a configuration that only the helper understands.
