iPhone was launched in 2007 by Apple Inc. It redefined the smartphone arena with its unique design, touch screen, and refreshing user interface. Apart from telephonic features and support, it bridged the Internet experience gap prevalent in other smartphones. It is loaded with the Safari web browser, an e-mail client, and an iPod, for a complete web experience.

Web apps
The interface is consistent with menu bars on top, and also at the bottom, when necessary.
