So what is a web app?

Web apps are simply responsive html based websites that are able to be loaded and used independently of your devices usual web browser
As such they work on most mobile devices and a range of screen sizes and do not require redevelopment as new devices or operating systems become available

Native Apps, in contrast, need to be updated by the developer as Apple and others release new operating systems and devices with new resolutions and screen sizes become available
On the other hand, native apps offer deeper integration with your device and generally loading faster and giving a better experience in respect to scrolling, zooming and so on
