Hybrid mobile apps are applications that are installed on a device, just like any other app.What differentiates them is the fact they possess elements from native apps, applications developed for a specific platform such as iOS or Android, with elements from web apps, websites that act like apps but are not installed on a device but are accessed on the Internet via a browser.
Hybrid apps are deployed in a native container that uses a mobile WebView object. When the app is used, this object displays web content thanks to the use of web technologies (CSS, JavaScript, HTML, HTML5).
It is in fact displaying web pages from a desktop website that are adapted to a WebView display. The web content can either be displayed as soon as the app is opened or for certain parts of the app only i.e. for the purchase funnel.
