HP webOS is a mobile operating system based on a Linux kernel, initially developed by Palm, which was later acquired by Hewlett-Packard.
webOS's graphical user interface design was led by Matias Duarte for use on devices with touchscreens. webOS uses multi-touch gestures to navigate on the touchscreen. The interface uses "cards" to manage multitasking. The user switches between running applications by a flicking gesture from left and right on the screen. Applications are closed by flicking a "card" up—and "off"—the screen.
webOS uses a feature, Synergy, to integrate information from many sources. Users can sign in to accounts on Gmail, Yahoo!, Facebook, LinkedIn, and Microsoft Outlook (via Exchange Active Sync) and integrate all of these sources into a single list. Calendars from multiple sources can be viewed together or one at a time. For messaging, Synergy combines all conversations with each contact into a single chat-style window. For example, instant messages and SMS text messages are viewed together.
The webOS web browser, simply named "Web," uses the Web-Kit layout engine.
By design, webOS uses a cloud-based approach rather than using a desktop sync client, but various third-party sync clients are available.
Officially vetted third-party applications are accessible from the device for wireless download by using the Hp App Catalog. Webos was a completely new platform. To enable backward compatibility to its former Palm OS, Palm commissioned a developer, MotionApps, to code and develop an emulator, called Classic, that operates with webOS version 1. PalmOS emulation has been discontinued in webOS version 2.0. MotionApps disengaged from Classic in 2010, citing HP Palm as "disruptive". Another source of applications is known as Homebrew. Homebrew is not directly supported by HP.
