Mobile users have neither the time nor the desire to read through a lot of help content before they can benefit from an application. What’s more, help content takes up valuable space to store and display.
iOS-based devices and their built-in applications are intuitive and easy to use, so people don’t need onscreen help content to tell them how to use the device or the apps. This experience leads people to expect all iOS apps to be similarly easy to use.
Gestures
People make specific finger movements, called gestures, to operate the unique Multi-Touch interface of iOS-based devices. For example, people tap a button to activate it, flick or drag to scroll a long list, or pinch open to zoom in on an image.
The Multi-Touch interface gives people a sense of immediate connection with their devices and enhances their sense of direct manipulation of onscreen objects.
People are comfortable with the standard gestures because the built-in applications use them consistently. Their experience using the built-in apps gives people a set of gestures that they expect to be able to use successfully in most other apps.
