What is the difference between a web app and a native app?
A web app is a web version of a native app. It is based on internet standards like HTML and CSS. This app is called via the browser of your smartphone. AppYourself uses the latest technologies of the HTML5 standard for the web apps.
The web app does not require a download from the store. Instead, the app is opened directly via a URL (e.g. via QR code) and can be stored on the home screen. A native app is specially designed for an App Store and can only be accessed via this App Store (in the form of a download and subsequent installation on the smartphone).
