“Apps” is an abbreviation for “Applications” and the phrase has been coined to represent applications that we download from app stores to our mobile devices.
An App can have a different function or purpose than your main website, and often the App is used to emphasize your brand.
They are built for common platforms, such as Android and iOS operating systems or both.
Your website can also be wrapped in an ‘app wrapper’ and ensure that functions such as finger swiping movements and hovering (which can be done on web but not on iPads for example) are handled. The application is then downloaded to your device such as an iPad from your App library in iTunes for example and is viewed separately to your device website browser.
